They spent the next three months traveling the world together, but ultimately, their romance couldn't make it past the summer. By September 2016, they were done.

"The Big Bang Theory" star Kaley Cuoco first hinted at her crush on Henry Cavill on Twitter in June 2013. By early July, there were reports that they were dating. Within days, they were photographed holding hands outside a grocery store in the Los Angeles area, confirming their rumored romance. But then — faster than a speeding bullet — the actress and the "Man of Steel" star had called it quits. The breakup reports hit the Internet on July 11 — just eight days after their grocery store date.

Jennifer Lopez and Drake first sparked romance rumors in late 2016. Within weeks, friends were telling People magazine that the superstar was "smitten" with the rapper. They spent New Year's Eve together, exchanged pricey gifts and hung out with her kids, but ultimately, things never got too serious between them… maybe because J.Lo started spending time with Alex Rodriguez, from whom she's since split, that March.

It was the fast-food order heard round the world: In August 2018, Ben Affleck infamously hit up a Jack in the Box drive-thru in the Los Angeles area with his new companion, Playboy model Shauna Sexton. (Their very public outings together were the first indication that the actor and his longterm girlfriend, "Saturday Night Live" producer Lindsay Shookus, had called it quits.) Ben and Shana reportedly continued dating when the A-list actor went to rehab but were over by mid-October.

It was the romance no one saw coming: In August 2019 — a day before she announced that she and Liam Hemsworth were calling it quits after less than a year of marriage — Miley Cyrus was snapped smooching Brody Jenner's former partner, Kaitlynn Carter. After that, the two women were practically attached at the hip. Just a month into their relationship, there were even reports that they were living together. But just as quickly as they started, they were through. Miley and Kaitlynn split in September 2019, and the singer-actress moved on almost immediately with Cody Simpson, from whom she split in the summer of 2020.

Back in 2011 — not long before she became Mrs. Ryan Reynolds — Blake Lively enjoyed a five-month romance with another one of Hollywood's most desirable leading men: Leonardo DiCaprio. The duo made headlines when they were seen together during the Cannes Film Festival in May, but by October, she'd moved on with her "Green Lantern" co-star. Blake and Ryan tied the knot less than a year later.

Demi Lovato and Max Ehrich infamously started dating, moved in together, got engaged and broke up all within the span of just six months (from March to September 2020).

It was a huge deal when Brad Pitt was seen spending time with German model Nicole Poturalski in the summer of 2020. The duo sent shockwaves throughout Hollywood when they were spied on a "romantic getaway" in the South of France in August. Just two months later, though, multiple media outlets reported that they'd split "a while back." Said an Us Weekly source, "They had a short-lived relationship that was never too serious."

This very cool (but ultimately incompatible) couple reached their peak then crashed and burned in less than six months. Ariana Grande and comedian Pete Davidson set the rumor mill ablaze when they began dating in May 2018 not long after splitting from their previous partners, rapper Mac Miller and writer-actress Cazzie David, respectively. Just a month later, Ari and Pete revealed they were engaged… but they called it quits less than five months later in October 2018. Talk about a whirlwind romance!

The world let out a collective "huh?" when Kate Beckinsale's flirtation with Pete Davidson at a 2019 Golden Globes party turned into a relationship. The age-mismatched duo (there's a 20-year gap between them) weren't shy about publicly expressing their affection for one another during their brief but intense romance, which came to an end after just a few months.

Pete Davidson has a very clear modus operandi when it comes to love. In late August 2019, news broke that the "Saturday Night Live" star was dating Andie MacDowell's daughter, "Once Upon a Time… in Hollywood" and "The Leftovers" actress Margaret Qualley. After that, they got serious fast. The young lovers went big for their official debut: The same month they were first linked, he joined her at the 2019 Venice Film Festival. (He was photographed sitting behind her and Anthony Mackie at the premiere of "Seberg.") But less than two months later, it was over.

Pete Davidson enjoyed a whirlwind romance with Kaia Gerber too. The duo were first linked in the wake of his breakup from Margaret Qualley in late October 2019. A month later, they were snapped holding hands as he joined her at a friend's wedding in Miami. But it wasn't meant to be: They called it quits after the holidays when he went to rehab.

"Euphoria" co-stars Zendaya and Jacob Elordi apparently heated things up for a hot minute! While neither ever confirmed a romance, they were seen vacationing together in Greece in August 2019, catching a train together in his native Australia in November 2019 and looking very cozy in both New York City in February 2020 — he was photographed kissing her forehead — and in Los Angeles at a flea market a month later. "They started as close friends but it became romantic after their show ended," a source told E! News in early 2020, adding that the pair had been "inseparable since last summer." However, it seems their romance wasn't anything serious — Jacob started a relationship with model Kaia Gerber in September 2020.

Just four months after Rebel Wilson debuted her new boyfriend, Jacob Busch, on Instagram, they were done. The duo, who reportedly grew close amid the coronavirus pandemic, made their red carpet debut as a couple at an event in Monaco in September 2020, but the Anheuser-Busch scion's regular appearances on the actress's Instagram feed came to an end after Christmas Eve. Rebel reportedly dumped him via text in mid-January 2021.

Fans were thrilled when Bill Hader and Rachel Bilson made their red carpet debut as a couple at the 2020 Golden Globes just two months after they first sparked romance rumors by dining together in Los Angeles. Sadly, by July, they'd gone their separate ways.

Michelle Rodriguez and Cara Delevingne first indicated they were a couple in January 2014 when they were caught on camera packing on the PDA during a basketball game in New York City. They were practically attached at the hip after that… until July, that is, when the "Fast & Furious" franchise star, who's 14 years older than the British model-actress, was suddenly seen making out with Zac Efron. Speaking of the former "High School Musical" star…

In early July 2014, Michelle Rodriguez was seen making out with Zac Efron — who's nearly 10 years her junior — during a romantic vacation in Sardinia, Italy. Their relationship fizzled out, however, after they got their fill of horseback riding, boating, dirty dancing, romping on the beach and globetrotting. By late August, they'd called it quits. The following January, Michelle admitted during an interview that she "couldn't last more than six months" in a relationship because she's a "lone wolf."

Nick Jonas and Kate Hudson sparked dating rumors after they were photographed together at Walt Disney World in Orlando in September 2015. Us Weekly soon confirmed they were hooking up after being introduced by Nick's "Scream Queens" co-star Oliver Hudson, Kate's brother. Their fling came to a mutual end within a few months. "Kate's incredible," Nick told Complex magazine of the actress, who's 14 years his senior, in early 2016. "We had an unbelievable connection as two humans who just admire things about each other, and see something in each other that's beautiful."

Naomi Campbell and Liam Payne first sparked romance rumors in January 2019 when fans noticed their flirty behavior on Instagram. Then in February, there were reports that the age-mismatched pair had been secretly dating since late 2018. By mid-April, however, the supermodel had reportedly gotten bored with the singer, who's 23 years her junior, and decided to "let things fizzle out."

Joe Jonas and Gigi Hadid were the "it" couple of summer 2015 — they even walked a red carpet together! But just five months after they were first linked, they'd gone their separate ways. The model wasted no time moving on with Zayn Malik: They were off and on for a while before reuniting in late 2019 and welcoming a daughter in 2020. Gigi enjoyed another headline-making and very short romance during one of their breaks…

In the months immediately following his time on "The Bachelorette" in the summer of 2019, Tyler Cameron and Gigi Hadid were practically inseparable — he even accompanied her and her family to her grandmother's funeral in the Netherlands. But less than two months after they first stepped out together, they were over, paving the way for the blonde beauty to reconcile with off-and-on love Zayn Malik, with whom she welcomed a daughter in 2020.

Andrew Garfield and Rita Ora raised eyebrows when they were first romantically linked in November 2018. It turned out to be the real deal: Things were so serious between them, they celebrated Christmas together. By March 2019, however, he'd reportedly dumped her over her spotlight-loving ways.

In October 2020 — after Shia LaBeouf and Margaret Qualley co-starred in a super-steamy music video — the Internet erupted with whispers they'd been secretly dating since that summer. In December, they proved the rumors were true by packing on the PDA at a Los Angeles airport. Just a few weeks later, though, People magazine reported that they'd called it quits in the wake of allegations Shia abused several of his former loves.

Pamela Anderson made headlines in January 2020 when she married producer Jon Peters — a longtime pal whom she'd previously dated in the late '80s (pictured) — after just three days of texting. Less than two weeks into their non-legally-binding marriage (they never filed the paperwork to make their union official), she reportedly realized that she'd "made a terrible mistake" and pulled the plug.

Lana Del Rey's relationship with "Live PD" star Sean "Sticks" Larkin was a total whirlwind romance: They were first linked in September 2019, went Instagram official that December, made their red carpet debut as a couple at a pre-Grammys party in January 2020 and called it quits less than two months later. The singer wasted no time moving on: In December 2020, People magazine broke the news that she'd gotten engaged to her secret boyfriend, model-singer Clayton Johnson, whom she met on a dating app earlier that year.

In September 2019, Evan Peters and Halsey were snapped holding hands at a theme park in the Los Angeles area. Us Weekly reported that they'd been dating for "several weeks" at the time. The following month, the pair made their red carpet debut as a couple at a Halloween-themed party for his show "American Horror Story." By January 2020, they'd reportedly moved in together. But all good things must come to an end! In March, Halsey deleted all traces of Evan from her Instagram feed, indicating they'd split after about six months of coupledom.

When Scott Disick started spending time with Sofia Richie back in mid-2017, he was actually in the midst of a hot romance with another young star: Bella Thorne. The singer-actress even traveled from Los Angeles to Cannes, France, to spend time with the father of three, who quickly revealed his playboy ways, leaving her feeling "used." Bella headed home early, leaving Sofia to squeeze her way into Scott's heart. Though the former "Shake It Up" star continued seeing Scott for a couple more months after that, it was ultimately the younger model who got him to commit. Speaking of Sofia…

Sofia Richie spent the summer of 2016 summer lovin' all over Justin Bieber during a break from his off-and-on relationships with Selena Gomez and Hailey Baldwin. The globetrotting romance — which caused major drama for both Selena and Hailey — was over by September.

It seemed like the real deal for Chrishell Stause and Keo Motsepe, who fell for each other while shooting season 29 of "Dancing With the Stars" during the fall of 2020. (He was partnered with Anne Heche, while she shimmied with his BFF, Gleb Savchenko.) In early December 2020, amid rumors Chrishell was somehow involved in Gleb's split from longtime love Elena Samodanova, she and Keo debuted their relationship on Instagram. They then spent the holidays together, and by mid-January 2020, they'd become "pretty much inseparable." An Us Weekly source said at the time that they had "a great relationship" that "blossomed pretty quickly" — she "clearly has strong feelings" for him, while he "worships the ground she walks on" and "is so wrapped around her finger," said the insider. But the following month, E! News reported that they'd gone their separate ways. The "Selling Sunset" star later blasted Keo on Instagram, saying she caught her boyfriend of a few months lying — though she declined to reveal what he lied about — and started to wonder if he "could even order a coffee without lying."

Meghan King's relationship with Christian Schauf seemed super-serious but ultimately turned out to be nothing more than a rebound romance following her late-2019 split from husband Jim Edmonds. The former "The Real Housewives of Orange County" star and the "Life Uncharted" podcast host were first linked in May 2020. They went Instagram official later that month, and in July, Christian revealed that they'd already discussed marriage. By Thanksgiving, however, it was over.

It was kind of a big deal when Jim Carrey and Ginger Gonzaga revealed they were a couple at a Golden Globes pre-party in January 2019. The very next day, the "Kidding" co-stars took it up a notch by posing together on the red carpet at the annual award show. But that was the last anyone heard of them as a couple. That October, People magazine reported that they'd quietly broken up months earlier.

Just two months after country star Cole Swindell debuted his relationship with wrestler Barbie Blank at the 2019 ACM Awards in April, they called it quits. The duo first sparked romance rumors that February.

Bachelor Nation fans were super-shocked when Victoria Fuller, who competed for Peter Weber's heart on season 24 of "The Bachelor" in early 2020, started spending time with Chris Soules, who headlined season 19 of "The Bachelor" in 2015, in his native Iowa amid the coronavirus pandemic. Ultimately, their hot-and-heavy quarantine romance wasn't meant to be: By that September, they'd called it quits.
