Join us as we take a look at all the stars celebrating their 50th birthdays in 2023…
Mario Lopez took to Instagram on Oct. 10 to mark his 50th birthday by sharing a video of himself shirtless in a boxing gym: "I woke up 50 years old today — half a century, I can't believe it! I feel good, I guess — I don't know what 50 is supposed to feel like. All I know is it's a time to kind of pause and reflect on how I got here and what's to come. I'm just gonna keep trying to work hard, stay focused on doing the right thing and hopefully the right things will continue to happen," he said, adding that he was "feeling very blessed."
He went on to thank "all the people who helped me make it to this point."
"Hopefully we'll see you for another 50!" he concluded the brief clip.
He continued to reflect on his big day in the caption, writing, "The term 'milestone' implies that turning 50 is a turning point. Not just another year older — it's a year that holds significance for how you see the road ahead and the legacy you hope to leave behind. I feel very blessed and I don't take anything for granted… 5 decades down, 5 more to go."
He added hashtags for "just getting started" and "blessed."

Steve Burns — the original host of the beloved Nickelodeon show "Blue's Clues" — celebrates his 50th birthday on Oct. 9.
After launching the show 27 years ago in 1996, Steve — who earned a Daytime Emmy nod for his work on the children's television program — abruptly left in 2002.
Two decades later in 2022, he revealed what happened.
"I didn't know it yet, but I was the happiest depressed person in North America," he told Variety. "I was struggling with severe clinical depression the whole time I was on that show. It was my job to be utterly and completely full of joy and wonder at all times, and that became impossible."
Donovan Patton took over hosting duties until the first iteration of the show ended in 2006; Josh Dela Cruz became the host for a reboot, "Blue's Clues & You," that launched in 2019.
After leaving "Blue's Clues," Steve — who moved out of busy Brooklyn and now lives a quieter life in the Catskill mountains — made music, releasing a few albums as a solo artist and with his band. (A track from his 2003 album, "Songs for Dustmites," became the theme song for the CBS sitcom "Young Sheldon.")
Steve, who's long done voice work, has appeared on the reboot of the show that made him famous and in 2022 appeared alongside the show's other hosts in the movie "Blue's Big City Adventure."

On July 23, political pop culture figure Monica Lewinsky turned 50. She's now been famous — for better or for worse — for half her life: It was 25 years ago that the Drudge Report broke the news of a major scandal involving the former White House intern and then-President Bill Clinton.

Actress, activist and professional poker player Shannon Elizabeth — who after rising to fame in "American Pie" founded the Shannon Elizabeth Foundation to conserve the natural environment of endangered habitats and animals — turned 50 on Sept. 7.
She took to Instagram to reveal how she celebrated her big birthday: "Thank you for all the birthday wishes! My hubby is taking me off the grid now for a week deep in the bush in Botswana! So please forgive me if you don't hear from me… I'll be with the animals. Lots of love from AFRICA!" she captioned a slideshow of photos from Botswana.
It's hard to believe, but Shannon looks almost exactly the same 24 years after she played foreign exchange student Nadia for the first time (see for yourself here and on her Instagram page).
In February 2023, she revealed during an appearance on the "Inside of You With Michael Rosenbaum" podcast that she was only paid "a couple thousand" dollars for her work in the first "American Pie" movie but "didn't care" because "it was my first studio film," she explained.
But she repeatedly turned down offers to reprise her role in the 2001 sequel until producers upped her salary. "I walked away from a lot of offers many times," she said. "My lawyer and my manager and agent all thought I was crazy. They were pushing me to say yes. I just kept saying no. I don't know why — I guess I had a number in my head I felt like they should pay and I got them to that number. You get 15 minutes, so you gotta milk it."
Her last movie was 2020's "Playing With Beethoven" — she'll next appear on screen in 2023's "Alone Today" — but in recent months, she's been co-directing a docuseries about a blind black rhino named Munu who's been cared for by her foundation for wildlife conservation (which is rooted in the nonprofit dog and cat rescue group, Animal Avengers, that Shannon founded in 2001).
