Child stars of the '70s: Where are they now?

They grew up before our very eyes, but what happened to our favorite child stars of the '70s after they graduated to adulthood? Wonderwall.com has the answer to that question in honor of actress Erin Murphy's 54th birthday on June 17, 2018. The little cutie and her fraternal twin sister, Diane, originally shared the part of Tabitha Stephens on "Bewitched," but Erin took over the role entirely as the girls began to age and look less alike. She appeared in more than 100 television commercials but retired from acting on television after "Bewitched" ended in 1972. Now keep reading to see how she and more child stars of the '70s have changed over the years…

Erin Murphy, who was a cheerleader and the homecoming queen at her high school, attended San Diego State University for two years. Since then, she's worked as a casting director, a makeup artist, a fashion stylist, an acting teacher, a motivational speaker and a stunt double for actress Virginia Madsen. She returned to acting in 2010 and has since had a few small roles in mostly under-the-radar projects. She also appeared on-camera as an infomercial host and television correspondent for E! and FOX Reality Channel. Erin starred on Hulk Hogan's celebrity championship wrestling series for CMT, in which she trained as a professional wrestler and used the name "Mistress of Mayhem" (aka M.O.M.). She has six sons from three marriages and is currently married to businessman Darren Dunckel.

Maureen McCormick played squeaky-clean eldest daughter Marcia Brady on "The Brady Bunch" during the '70s. She also voiced the redesigned Chatty Cathy doll in 1970.

Although she was idolized by '70s girls (and lusted after by '70s guys), Maureen McCormick hit a rough patch — both personally and professionally — after "The Brady Bunch." The actress got hooked on cocaine and Quaaludes and suffered from bulimia, depression and paranoia. As a result of her drug addiction, Maureen became extremely unreliable and got a bad reputation in Hollywood. Things got really bleak, and, according to her 2008 memoir, "Here's the Story: Surviving Marcia Brady and Finding My True Voice," she went so far as to trade sex for drugs. Maureen met her husband, Michael Cummings, at a church event in the early '80s, and the couple wed in 1985. She later got sober and started taking anti-depressants. In 1989, she gave birth to daughter Natalie. Maureen continues to work in Hollywood, mainly on reality TV. She won Season 5 of "Celebrity Fit Club" in 2007 and competed on Season 23 of "Dancing With the Stars" in 2016.

Quinn Cummings shot to fame as precocious Lucy in 1977's "The Goodbye Girl," a role that earned her an Oscar nomination for Best Supporting Actress. Just 10 years old when she was nominated, Quinn is the third youngest actress to receive this honor. The following year, she joined the cast of "Family" as adopted daughter Annie.

Tired of living in the public eye, Quinn Cummings — who hasn't been publicly photographed since 2009 — quit acting in the early '90s. She tried her hand as a TV writer before scoring a job recruiting writers to publish short stories online. In 2005, Quinn started a blog called The QC Report and has since written three memoirs: "Notes from the Underwire: Adventures from My Awkward and Lovely Life," "The Year of Learning Dangerously: Adventures in Homeschooling" and "Pet Sounds: New and Improved Stories from the QC Report." In 2000, Quinn welcomed daughter Anneke with boyfriend Donald DiPietro, an Internet software executive. Motherhood inspired Quinn to invent the HipHugger baby-carrying sling. She was president of the company until she sold it in 2006.

This redheaded moppet shook her tambourine as Tracy on "The Partridge Family" from 1970 to 1974. Though it was only her second audition ever, Suzanne Crough had a lot of experience to pull from to play the youngest member of the musical family: In real life, she's the youngest of eight kids!

Once the '70s came to an end, so too did Suzanne Crough's time in Hollywood. She went on to nab a few roles, but her last acting credit was the 1980 TV movie "Children of Divorce." In April 2015, the former child star (pictured in 2014) died at age 52 of a rare heart condition, leaving behind two daughters, Samantha and Alexandra.

Barry Williams had guest roles on "The Mod Squad," "Here Come the Brides" and "Bartleby, the Scrivener" before being cast as Greg Brady on "The Brady Bunch" at age 15. He became one of the big teen idols of the 1970s and continued to star on the show until 1974.

Following the cancellation of "The Brady Bunch," Barry Williams began acting in the theater. He toured with a number of productions including "Grease," "The Sound of Music," "West Side Story" and "Romance/Romance" through the 1980s while also starring in various "Brady Bunch" TV movie reunions including the 1988 holiday flick "A Very Brady Christmas." In the 1990s, he wrote a New York Times bestselling novel, "Growing Up Brady: I Was a Teenage Greg," and continued to star in TV movies. Today, Barry is a spokesperson for the MeTV television network where he promotes "The Brady Bunch" and other classic TV series. The father of two is currently married to third wife Tina Mahina.

Alison Arngrim lost out on playing both Laura and Mary Ingalls before being cast as nasty Nellie Oleson on "Little House on the Prairie." The young actress donned a wig to sport Nellie's signature sausage curls.

Alison Arngrim had trouble escaping her "Little House on the Prairie" character, which made it difficult for her to nab roles after the show went off the air. She later turned to stand-up comedy. Alison is very active with a number of charitable organizations, including the National Association to Protect Children, which aims to protect kids from abuse and exploitation. It's a cause that hits close to home for Alison, who was sexually abused by her brother when she was a child. In 2010, she released her memoir, "Confessions of a Prairie B—-: How I Survived Nellie Oleson and Learned to Love Being Hated," which became a New York Times bestseller. Alison met her husband, musician Robert Schoonover, while volunteering at AIDS Project Los Angeles. The couple walked down the aisle in 1993. She was previously married to writer Donald Spencer.

Talk about an early start! Brooke Shields modeled in her first ad for Ivory Soap when she was only 11 months old. At the age of 12, she landed the lead role as child prostitute Violet in the controversial 1978 film "Pretty Baby." She continued to model and when she was 14, became the youngest person to snag the cover of Vogue.

In 1980, a teenage Brooke Shields continued to make waves on the big screen with "The Blue Lagoon." Her controversial roles ultimately helped her get noticed, and in 1996, she hit it big with her own sitcom, "Suddenly Susan." A year later, she married tennis pro Andre Agassi, but they divorced just a year before her series ended in 2000. The NYC native continued to make small cameos on shows like "Friends" and "Nip/Tuck" before "Lipstick Jungle" hit the air in 2008. The show only lasted for a year, but Brooke continues to pop up on television from time to time. In 2001, she wed writer and producer Chris Henchy, with whom she shares two daughters.

Melissa Gilbert, who cut her teeth with commercials when she was just a tot, was 10 years old when she scored her big break with the 1974 series "Little House on the Prairie." The NBC show, which is based on Laura Ingalls Wilder's "Little House" novels, won multiple Emmys and even landed the adorable redhead two Young Artist Awards.

Melissa Gilbert continued acting predominantly on television after "Little House on the Prairie." She starred on "Sweet Justice" in the '90s, popped up on "Babylon 5" and had a stint on "Secrets and Lies" in 2015. She also starred in a musical rendition of "Little House" in 2008. In 2012, she went out on a limb and tried her hand at ballroom dancing, coming in fifth place on the 14th season of "Dancing with the Stars." Melissa — who detailed her struggles with drugs and alcohol in her 2009 memoir "Prairie Tale" — has a son, Dakota, from her four-year marriage to actor Bo Brinkman. Her second marriage — to Bruce Boxleitner, with whom she shares son Michael — ended after 16 years in 2011. She wed actor-director Timothy Busfield in 2013. The former child star launched a campaign for Congress in Michigan's 8th district in early 2016 but was forced to drop out of the race due to a spinal injury. She also served as president of the Screen Actors Guild for two terms in the aughts.

Many actors spend their whole careers hoping to pick up a big award, but little Ricky Schroder was only 9 years old when he won a Golden Globe in 1980 for his performance in the 1979 film "The Champ." Where do you go from there?

Ricky Schroder continued to strive for greatness on TV series like "NYPD Blue" and "24." Though he never did win another Golden Globe, he came close with a nomination in 1991 for his work in the miniseries "The Stranger Within." The Brooklyn native went on to marry Andrea Bernard in 1992 and had four children. He co-starred with daughter Cambrie on the 2013 Hallmark movie "Our Wild Hearts." Most recently, he starred on the 2016 TV movie "Dolly Parton's Christmas of Many Colors: Circle of Love." In 2016, he and his wife of nearly 24 years, Andrea, revealed plans to divorce.

A 15-year-old Valerie Bertinelli got her start in 1975 on the sitcom "One Day at a Time." The Delaware native rose to fame alongside fellow child star Mackenzie Phillips.

Valerie Bertinelli went on to marry rocker Eddie Van Halen in 1981. The couple ultimately divorced but had a son together, Wolfgang Van Halen. In 2009, she signed on as a spokesperson for the weight-loss program Jenny Craig and wrote two books about her diet struggles: "Losing It: And Gaining My Life Back One Pound at a Time" and "Finding It: And Satisfying My Hunger for Life without Opening the Fridge." Valerie married Tom Vitale in 2010 and recently starred alongside Betty White, Wendie Malick and Jane Leeves on the popular TV Land series "Hot in Cleveland." She currently hosts "Valerie's Home Cooking."

Christopher Knight began his Hollywood career in 1969 when he was cast to play middle son Peter Brady on "The Brady Bunch." The young actor grew into a teen idol and continued to star on the show until it wrapped in 1974.

Disillusioned with Hollywood, Christopher Knight stopped acting in the 1980s (with the exception of the "Brady Bunch" spin-offs) and began a career in tech and business. The self-described "geek" co-founded Visual Software, a pioneering 3D graphics company, in 1991 and launched multiple other successful tech companies throughout the '90s. In the 2000s, Christopher decided to return to TV and experienced a resurgence in fame after starring on "The Surreal Life" and a spin-off show, "My Fair Brady," with his then-girlfriend and "Surreal Life" co-star Adrianne Curry. The two got engaged and married on the show but eventually divorced in 2011. Today, Christopher is married to his fourth wife, Cara Kokenes, and last starred in "Where the Fast Lane Ends."

Kristy McNichol launched her career as a television actress in the mid-'70s. Her big breakthrough came when she starred as Letitia "Buddy" Lawrence on "Family" from 1976 to 1980. She earned four Emmy nominations — and two wins in 1977 and 1979 — for her performance. In 1978, Kristy and her actor brother, Jimmy McNichol, recorded an album for RCA Records, creatively titled "Kristy & Jimmy McNichol."

Kristy McNichol continued to work steadily throughout the '80s until her career began to taper off in the '90s amidst rumors of drug use and increasingly erratic behavior. She was diagnosed with bipolar disorder in 1992 and left her job on the sitcom "Empty Nest" shortly after. She returned to the show for the series finale in 1995 and has only appeared on camera once since then: in the 2012 short "Call to Action to Mayor Bloomberg: Sodas & Soap Operas." On Jan. 6, 2012, Kristy publicly came out as a lesbian. She currently lives in Los Angeles, where she teaches acting at a private school with her partner of 20 years, Martie Allen.

"Marcia, Marcia, Marcia!" Eve Plumb made that line famous while starring as middle sister Jan Brady on "The Brady Bunch" in the 1970s. She was only 11 years old when she was cast in 1969. Eve went on to break away from her good-girl image by starring as a teenage prostitute in the NBC TV movie "Dawn: Portrait of a Teenage Runaway" in 1976.

Eve Plumb had numerous guest appearances on TV during the 1980s and '90s including roles on "The Facts of Life," "Murder, She Wrote," "Lois and Clark: The New Adventures of Superman," "All My Children" and "That '70s Show." She also reprised her role as Jan Brady in many "Brady Bunch" spin-offs such as "The Brady Girls Get Married" and "A Very Brady Christmas." Eve most recently appeared on NBC's "Grease: Live," the Hulu series "The Path" and the CBS drama "Blue Bloods." The former child star, who enjoyed a successful painting career in addition to her acting, has been married to Ken Pace since 1995.

In 1970, Danny Bonaduce struck gold with his role as Danny Partridge on "The Partridge Family." The series, starring Shirley Jones and David Cassidy, ran until 1974 and was even nominated for two Golden Globes.

Danny Bonaduce went on to struggle with drug addiction after "The Partridge Family" came to an end. He even admitted that he was homeless for a period of time even though he was still making cameos on TV shows like "CHiPS" in the 1980s. The Pennsylvania native spiraled out of control and was arrested once in 1990 for trying to buy illegal substances and then again in 1991 over a dispute with a prostitute. Fortunately, Danny cleaned up his act: By 1994, he was hosting his own radio show, "The Danny Bonaduce Show." Danny has been married three times (most currently to Amy Railsback) and has two kids, Count Dante Jean-Michel Valentino Bonaduce and Countess Isabella Michaela Bonaduce. He continues to voice a radio program in Seattle, has found a second calling as a host and reality TV personality and appeared on the ABC revival of "Battle of the Network Stars" in June 2017.

A 7-year-old Justin Henry starred as the adorable Billy Kramer alongside Dustin Hoffman and Meryl Streep in the smash hit "Kramer vs. Kramer" after being discovered (with no acting experience) by his next-door neighbor, who was a casting director. Justin became the youngest person ever to be nominated for an Oscar when he was nominated for Best Supporting Actor for his work in the film.

Justin Henry acted in a handful of films throughout the '80s before taking an almost decade-long hiatus to focus on his studies at Skidmore College. He returned to the screen in the mid-'90s after earning a B.A. in psychology in 1993. His biggest role since his return to the screen was a two-episode arch on "E.R." in 1997. The following year, he founded the Slamdunk Film Festival, which ran from 1998 until 2003. Justin currently lives in Los Angeles where he's the sales director at eyeReturn Marketing.

Susan Olsen starred as pig-tailed Cindy Brady on "The Brady Bunch." The 7 year old was cast after making a handful of television appearances in small roles.

Susan Olsen, who had surgery to correct the lisp for which her "Brady Bunch" character was known, appeared in several "Brady" spin-off projects, but ultimately, her acting career ended with the franchise — even though she trained at the American Academy of Dramatic Arts. Susan has since worked as a graphic designer: She marketed a brand of glow-in-the-dark shoes for Converse and illustrated children's books. The twice-divorced actress lives with her current husband, Chris Fonseca, in Los Angeles. She has worked with the cat-rescue group Precious Paws and was fired from her hosting job at LA Talk Radio in late 2016 after a feud with a guest turned ugly. (She sent the man homophobic private messages on Facebook.) Susan has one son, Michael.

Tatum O'Neal, the daughter of actors Ryan O'Neal and Joanna Moore, crashed onto the scene in 1973 when she starred opposite her dad in "Paper Moon." She became the youngest actor ever to win an Oscar when she took home the award for Best Supporting Actress at age 10. (Yes, for her first film!) Tatum then became the highest paid child actor in history (at the time) when she won a role in "The Bad News Bears" — she reportedly made $350,000. She appeared alongside her dad again in 1976's "Nickelodeon." When the actress was 12, a 17-year-old Michael Jackson fell hard for her. MJ said later that Tatum was his first love, but she claims they only kissed once.

Tatum O'Neal went on to struggle with drug addiction — specifically heroin — as an adult. In her 2004 autobiography, "A Paper Life," the actress claimed that she was molested by her father's drug dealer at the age of 12 and accused dad Ryan O'Neal of drug-fueled emotional and physical abuse. Tatum married tennis player John McEnroe, with whom she has three children, in 1986. They split in 1992, sparking a fierce custody battle that Tatum eventually lost. In 2008, Tatum was arrested for buying crack cocaine near her apartment in New York City and charged with misdemeanor criminal possession of a controlled substance. The actress and her father have maintained a turbulent relationship over the years, though they briefly reconciled for the cameras on the 2011 OWN reality show "Ryan and Tatum: The O'Neals." In 2015, she made headlines when she briefly dated comedian Rosie O'Donnell. Though she never achieved the same level of success as she did as a child, Tatum has appeared on-screen steadily as an adult.

Mike Lookinland was only 9 when he was cast to play the youngest Brady brother, Bobby, on "The Brady Bunch." He continued to star on the hit show until its cancellation in 1974.

After starring on "The Brady Bunch," Mike Lookinland starred in the 1974 disaster blockbuster film "The Towering Inferno" and on the 1970s TV shows "The Secrets of Isis" and "Little House on the Prairie." Throughout the '80s and '90s, he appeared in all the "Brady" spin-off shows and movies including "A Very Brady Christmas" and "The Bradys," but didn't have many other roles. Mike spent the next several years working as a television camera operator before leaving show business altogether in 2003. He now operates a decorative concrete business with his wife of 31 years, Kelly Wermuth, in Salt Lake City. The couple share two sons, Scott and Joe.

Linda Blair started her career as a model and commercial actress, but she was anything but pretty when she horrified the world as possessed child Regan MacNeil in "The Exorcist." The portrayal earned many accolades, including an Oscar nomination for Best Supporting Actress, but also death threats, which prompted Warner Bros. to hire police to live with the Blair family for six months to ensure their safety. During the late '70s, Linda encounter the police again, though in a much different context. She was arrested by the Drug Enforcement Agency, along with 30 others, and charged with conspiracy to buy cocaine in Florida to be sold in Connecticut. When police searched Linda's purse, they found amphetamines, so she was also charged with possession. (The possession charge was later dropped, and the conspiracy charge was reduced.)

Linda Blair, who donned cat ears during a Halloween bash in 2016, struggled to resurrect her career after her troubles with the law. She continued to work steadily in small film and television roles, as well as on reality TV, but never achieved the success of her early years. "[My career] went down faster than the Titanic," she once said. The actress devotes much of her time to animal-rights organizations and charities and even launched her own: the Linda Blair WorldHeart Foundation.

The son of actors Shirley Jones and Jack Cassidy, Shaun Cassidy was destined for a career in entertainment. He focused on his schooling while his mom and brother, David Cassidy, appeared on "The Partridge Family." He stepped into the spotlight at age 19 in 1977 when his musical career took off, and shortly after, he was cast as Joe Hardy in "The Hardy Boys/Nancy Drew Mysteries." His single "Da Doo Ron Ron" hit No. 1 in America, and Shaun scored a Grammy nomination for Best New Artist. He went on to release two more albums in the '70s.

By the release of his third album, Shaun Cassidy's appeal as a teen idol had begun to fade. He took on a few guest-starring roles on various television shows throughout the '80s but then, as an adult, shifted his career focus from performing to writing and producing. (He produced and wrote episodes of the now-defunct 2017 series "Emerald City.") Shaun is currently married to Tracey Lynne Turner, with whom he has four children. (He has three more children from two previous marriages.) The family resides on a ranch outside Los Angeles.

Melissa Sue Anderson worked steadily on television starting in 1972 until she scored her breakout role as Mary Ingalls on "Little House on the Prairie" at age 11. Melissa was the only member of the cast to ever score an Emmy nomination for her work on the series. She later won an Emmy for a 1979 ABC Afterschool Special. She dated Lorenzo Lamas after they appeared together on "The Love Boat" and later, Frank Sinatra Jr., who was more than twice her age.

Melissa Sue Anderson continued working throughout the '80s, though she failed to land a major hit as an adult. She and her husband, television writer Michael Sloan, have two children, daughter Piper and son Griffin, and reside in Montreal, Quebec. (They became Canadian citizens in 2007.) In 2010, Melissa released her autobiography, "The Way I See It: A Look Back at My Life on Little House." She still appears occasionally in small television roles.

Leif Garrett launched his acting career when he was just 5 years old. He worked steadily throughout the '70s in small roles on television, and finally in "Three for the Road" and the "Walking Tall" movie franchise. He also recorded three albums in the '70s, and his single "I Was Made for Dancin'" was a huge hit. Leif found success as an actor and musician, but more importantly, he was a hit with the ladies, helping usher in the era of the teen idol. He dated many of his co-stars, including Kristy McNichol, Tatum O'Neal, Justine Bateman and Nicollette Sheridan, whom he was with for six years. In 1979, a 17-year-old Leif crashed his car while under the influence of Quaaludes and alcohol. The accident left his passenger, pal Roland Winkler, a paraplegic. Roland's family filed a $25 million negligence lawsuit against Leif. The suit was eventually settled out of court for $7.1 million.

Leif Garrett released two more albums in the '80s and continued working in film and television, though his career dramatically slowed in the '90s. In 1999, his longtime love, actress Elaine Bilstad, died of a heart problem, leaving him devastated. That same year, he was arrested in Los Angeles for allegedly trying to buy narcotics from undercover officers. Then on Jan. 14, 2006, when Leif was arrested on a subway platform for not having a ticket, police found drugs in his possession. He was sentenced to 90 days in jail and three years of probation after failing to complete a court-ordered drug rehab program. Leif was arrested again on Feb. 1, 2010, for possession of narcotics. He was charged with a felony count of heroin possession. The performer appeared on "Celebrity Rehab With Dr. Drew" in 2010, but, sadly, his career has not been resuscitated.

Harvey Stephens terrified the world with his portrayal of the Antichrist in "The Omen" in 1976. The first-time actor, who was cast in the film when he was just 4 years old, dyed his hair black for the role — and ensured that no one would name their child Damien ever again.

Harvey Stephens was a one-hit wonder. He had a small role on a TV movie in 1980 and then disappeared from the screen until 2006 when he had a brief cameo as Tabloid Reporter No. 3 in the remake of "The Omen." The onetime child actor resides in England with wife Emma, with whom he has one child. At one time, he worked as a futures trader in the London stock market, and he's also been a property developer. Harvey and his tricycle occasionally appear at horror conventions and autograph signings.

Mackenzie Phillips, whose father is John Phillips of The Mamas and the Papas, got her start when she was just 12 years old in 1973's "American Graffiti." She worked steadily in film and on television until she landed the role of rebellious teen Julie Cooper on "One Day at a Time" in 1975. Mackenzie's career started to crumble when her on-set behavior grew increasingly erratic. In 1977, she was arrested for public drunkenness and cocaine possession.

Between 1980 and 1983, Mackenzie Phillips took several breaks from "One Day at a Time" to seek rehabilitation treatment for drug problems. Her career never recovered. She has continued to struggle with drug use, and on Aug. 27, 2008, she was arrested by the Los Angeles Airport Police on charges of possession of cocaine and heroin. She also appeared on the third season of "Celebrity Rehab With Dr. Drew." In Mackenzie's 2009 biography, "High Arrival," the actress recounted in detail her 10-year sexual relationship with her father, calling it "consensual." (The allegations have been denied by some members of the Phillips family.) Mackenzie continues to work occasionally on television. The twice-divorced actress is married to composer Keith Levenson and has a son, Shane.

Peter Ostrum had just one role during his short but sweet career as an actor: Charlie Bucket opposite Gene Wilder in "Willy Wonka & the Chocolate Factory." Talent agents discovered the sixth grader while he was performing with the Cleveland Playhouse children's theater. After "Willy Wonka," Peter was offered a three-picture contract, which he turned down before drifting into obscurity.

Peter Ostrum groomed horses and worked at the Delaware Equine Center in Pennsylvania during a break between high school and college. While he briefly considered returning to Hollywood, he ultimately decided to pursue a degree in veterinary medicine instead, and he earned his degree from Cornell University College of Veterinary Medicine in 1984. Peter now lives in rural New York state with his wife, Loretta Lepkowski, and their two children, Helenka and Leif. He currently practices at the Countryside Veterinary Clinic in Lowville, New York, and put his acting chops to work in a Pfizer-sponsored reality series, "Veterinarians On Call."

A 3-year-old Jodie Foster launched her career as a Coppertone Girl in one of the sunscreen brand's iconic commercials. After working steadily in television from the time she was 5, Jodie scored her first major breakthrough in 1976 by playing 12-year-old prostitute Iris in "Taxi Driver." The role landed her an Oscar nomination for Best Supporting Actress and sparked a career that continues to flourish today. She was the youngest person ever to host "Saturday Night Live" at the time (at just 14 years old), and she even briefly courted a career as a singer in the French pop music scene.

Jodie Foster didn't take home the Oscar during the '77 Academy Awards, but she made up for the loss by winning in 1989 for "The Accused" and in 1992 for "The Silence of the Lambs." The actress famously struggled with fan obsession: John Hinckley Jr. stalked Jodie while she was studying literature at Yale University, and on March 30, 1981, when she was a freshman, he attempted to assassinate President Ronald Reagan to get her attention. The mother of two remains fiercely protective of her personal life, most notably her sexual orientation, the identities of her children's father(s), and the method by which her sons were conceived. However, in January 2013, she publicly revealed that she's a lesbian while accepting the Cecil B. DeMille Lifetime Achievement Award during the 2013 Golden Globes. The following year, she married actress Alexandra Hedison. Jodie continues to work steadily, even as she's begun focusing on her career as a director, helming episodes of "Orange Is the New Black," "House of Cards" and "Black Mirror" as well as the George Clooney-Julia Roberts film "Money Monster" in recent years.

David Cassidy became an instant teen idol when he starred as Keith Partridge, the son of Shirley Partridge (played by step-mother Shirley Jones), on the 1970s musical-sitcom "The Partridge Family." He released five super-successful solo albums during his run on the show and became a globally recognized pop artist. His sold-out shows caused so much hysteria that a teen girl was killed in a crush at the front of the stage at one of his London concerts.

David Cassidy's career calmed down in the 1980s and '90s, but he still maintained some success in the music world. His 1985 single "The Last Kiss" went gold and he returned to the American Top 40 with his 1990 single "Lyin' to Myself." David's 2001 album "Then and Now" went platinum internationally and returned him to the top five on the U.K. album chart for the first time since 1974. The former teen idol continued to tour throughout his later years but sadly struggled with alcoholism. After a string of DUI arrests and rehab stints, David finally succumbed to his addictions in November 2017 when he died of liver and kidney failure brought on by years of alcohol abuse. David was married and divorced three times and had two children, son Beau and daughter Katie Cassidy, who found fame on TV's "Arrow."

Tanya Tucker belted her way into the spotlight when she was just 13 years old. Her single "Delta Dawn" was a huge hit, the first of many throughout the late '70s for the singer. But Tanya started drinking during her late teens, and she earned a reputation as a party girl when she moved to Los Angeles in 1978. She was romantically linked to Merle Haggard (who was 21 years her senior), Don Johnson, Andy Gibb, and most notably, fellow country star Glen Campbell (pictured).

Tanya Tucker moved to Nashville after she and Glen Campbell split in 1982. At that time, she was enjoying less commercial success while drinking heavily and using cocaine. She entered the Betty Ford Center in 1988 at her family's urging. Her career suffered as a result, but Tanya continues to make music today. She released her 24th studio album in 2009. She also starred on a reality show "Tuckerville" in 2005. Though she's never been married, she has three children.

Jackie Earle Haley got his start acting in TV commercials at age 6. He appeared in guest-starring roles on several hit '70s series including "The Partridge Family" and "The Waltons" before scoring his big break as baseball bad boy Kelly Leak in the "Bad News Bears" franchise.

Though he failed to land another project with the impact of "Bad News Bears" early in his career, Jackie Earle Haley continued working on television and in film until 1993, when he took a break and moved to San Antonio, Texas, to focus on directing and producing commercials. More than a decade later, he returned to the screen (at the prompting of pal and "Slab Boys" co-star Sean Penn) and sparked a resurgence in his career that eventually led to an Oscar nomination for Best Supporting Actor for his performance in "Little Children." Jackie still lives in San Antonio, though he's appeared in a number of recent hits since his 2006 return to the screen including "Watchmen," "Lincoln" and the 2014 "RoboCop" remake. Jackie currently lives with his third wife, Amelia Cruz, whom he wed in 2004, and has two children, Christopher and Olivia, with his second wife.

An 8-year-old Kathy Coleman starred as Holly Marshall on "Land of the Lost." It was only the second acting job for the actress. It would also prove to be her last!

When she was 19, Kathy Coleman married and moved to Fallon, Nevada, where she worked on her father-in-law's dairy farm with her husband for several years until they divorced around 1987. The couple has two children. Kathy has since moved back to Los Angeles, where she occasionally appears at fan events and conventions.

From 1974 to 1979, Ralph Carter starred as Michael Evans on "Good Times." It was his only on-screen role. He released an album, "Young and In Love," in 1976, and his two singles were hits on the disco scene. When he was 12, he was nominated for a Tony Award for best supporting or featured actor for his work in the Broadway musical "Raisin."

Ralph Carter failed to translate his status as a child star into a career as an adult actor. He sang in New York nightclubs during the '80s and wrote a play, but he's remained mostly out of the spotlight in recent years. He currently lives in New York City, where he participates in local theater and is involved in the African-American community. He reportedly married twice and had five children.

A 4-month-old Kim Richards made her acting debut in a diaper ad and went on to appear in 20 commercials by her fifth birthday. The young actress got her big break playing Prudence on "Nanny and the Professor," but 1975's "Escape to Witch Mountain" — in which she starred alongside Ike Eisenmann — was her first major film. (She also appeared alongside sister Kyle Richards in 1977's "The Car.")

Kim Richards' acting career slowly tapered off during the mid-'80s, and she eventually retired to focus on raising her four children: Brooke, Whitney, Chad and Kimberly. She returned to the big screen for a small role in 2006's "Black Snake Moan," appeared in the 2009 remake of "Escape to Witch Mountain," popped up on a 2015 episode of "Revenge" and had a part in "Sharknado 3: Oh Hell No!" Kim also appeared in Lady Gaga's 2013 "G.U.Y." music video. People know her best, though, for "The Real Housewives of Beverly Hills," on which she's appeared since 2010 — and for her headline-making issues with drugs and alcohol and problems with the law.

Erin Moran started acting at age 5 and worked continuously throughout the '70s. When she was 12, she was cast as feisty little sis Joanie Cunningham on "Happy Days," for which she is most well-known.

Erin Moran continued to play Joanie Cunningham on "Happy Days" spin-off "Joanie Loves Chachi" during the '80s. But once the series went off the air, she had a hard time landing acting roles. In 2008, she participated in the sixth season of "Celebrity Fit Club," during which she admitted that she only went on the show for money and not to lose weight. In July 2012, Erin and her "Happy Days" castmates reached a settlement with CBS over merchandising revenue, which amounted to a $65,000 payment, plus future royalties. But even that cash couldn't help Erin's sad situation. After her California home was foreclosed on in 2010, she and her husband, Steven Fleischmann, moved into his mother's Indiana trailer home. The couple found themselves on the street again in late 2012 after being kicked out of the trailer for their non-stop partying. Erin died suddenly from throat cancer at the age of 56 on April 22, 2017.

Brandon Cruz was just 5 years old when he scored his first hit series playing Eddie Corbett on "The Courtship of Eddie's Father." The actor worked steadily on television throughout the '70s until he landed a role in "The Bad News Bears," his only major film project.

Brandon Cruz took a nearly two-decade-long break from acting to focus on his music career. He fronted the hardcore punk band Dr. Know off-and-on between the early '80s and 2010 and briefly replaced Jello Biafra as lead singer of the Dead Kennedys in the early 2000s. Brandon returned to the screen in 1995 with a small role in "Safe" and he briefly appeared in 2004's "The Motorcycle Diaries." He's also worked as a drug and alcohol rehab counselor at Walking Miracles Recovery Center in Malibu and with A Minor Consideration, a watchdog group of former child stars whose mission is to look after the welfare of former and current child actors. Brandon wed Elizabeth Finkelstein in 1994. The couple has two children, son Lincoln and daughter Ruby.

Parker Stevenson caught the acting bug from his mother, a commercial actress, who dragged him to set when he was young. He starred on the series "The Hardy Boys/Nancy Drew Mysteries" during the late '70s.

Parker Stevenson continued to act throughout the '80s and '90s, most notably on hit shows like "Baywatch" and "Melrose Place." He's since appeared in TV and film projects here and there and in recent years has starred on the Netflix series "Greenhouse Academy." Parker married actress Kirstie Alley in 1983, but the two divorced in 1997 after 14 years of marriage. They share two adopted children, William True and Lillie Price.

After appearing in an uncredited role in the 1967 movie "Wait Until Dark," Robby Benson had a brief stint on the daytime soap "Search for Tomorrow." He then starred in many coming-of-age films of the '70s including 1976's "Ode to Billy Joe" and became one of the biggest heartthrobs of the decade.

Robby Benson continued to act throughout the '80s and '90s, but his most well-known role came in 1993 when he voiced the Beast in "Beauty and the Beast." He then transitioned to writing, penning a novel, "Who Stole the Funny? A Novel of Hollywood," and a memoir, "I'm Not Dead… Yet!" Married since 1982 to actress Karla DeVito, Robby has two children, daughter Lyric and son Zephyr.

Donny Osmond was one of the top teen idols of the '70s. After finding fame in the '60s with his brothers as part of their music group The Osmonds, Donny went solo in the early '70s and stole hearts with his hit cover of "Puppy Love." In 1976, Donny paired up with his younger sister, Marie Osmond, for their eponymous ABC variety show, which aired from 1976 to 1979.

Donny Osmond remained in the spotlight long after his teen heartthrob days. He married Debra Glenn in 1978 and went on to have five sons. He's continued working with sister Marie Osmond too. They co-hosted a talk show from 1998 to 2000 and have co-headlined a Las Vegas residency show since 2008. In 2009, Donny won the ninth season of "Dancing With the Stars."

Pamela Sue Martin started as a model but transitioned into acting during her late teens. In 1977, she debuted in the iconic role of Nancy Drew alongside teen heartthrobs Shaun Cassidy and Parker Stevenson on "The Hardy Boys/Nancy Drew Mysteries."

Pamela Sue Martin went on to star on "Dynasty" from 1981 to 1984. Since then, she's acted only occasionally, popping up on episodes of "That '70s Show" and "The L Word." She went on to marry and divorce three times and reportedly has one son.

Willie Aames appeared on several iconic TV shows of the '70s — from "Swiss Family Robinson" and "Family" to "Gunsmoke" and "The Odd Couple" — but it wasn't until 1977 when he debuted as Tommy Bradford on "Eight Is Enough" that he scored his big break.

Willie Aames continued acting throughout the '80s but also started to battle depression and a cocaine addiction. He became a born-again Christian in the '90s and starred as an evangelical superhero on the series "Bibleman" — which he also created, wrote and directed — from 1995 to 2002. Though he hasn't worked much in recent years, Willie has appeared in several TV movies as well as an episode of the sitcom "Date My Dad" in 2017. He also appeared on two seasons of "Celebrity Fit Club," first in 2005 and then in 2008. Willie has a son, Christopher, from his first marriage and a daughter, Harleigh, from his second marriage. He's currently married to wife No. 3, Winnie Hung.
