John Stamos sends fans wild with nude photo for 63rd birthday: ‘Have mercy’

John Stamos continued his annual tradition of posing in his birthday suit, as the Full House star sent fans into a frenzy with his incredibly muscular body.

John celebrated his 63^rd birthday on Wednesday with the photo, which saw him snapping a mirror selfie in his bathroom, his muscular torso on full display. The actor held his phone over his face, and artfully cropped the picture to stop just below his waist.

“63,” he captioned the cheeky photo, as friends and fans took to the comment section to exclaim over his risqué look. Kelly Rizzo, the wife of the late Full House actor Bob Saget, commented: “All I can think about is ‘what would Bob say’ right now. Happy birthday brother John I love you!” while a fan chimed in: “Have mercy!!”

Another wrote: “Not John Stamos with the thirst trap,” while a fourth declared: “You and Lenny Kravitz are raising the bar on how to age. Rock on.”

“63 is the new 36,” said another, as a sixth shared: “You Still Got It Dude.”

John is no stranger to naked selfies, having shared a photo of himself in an outdoor shower in celebration of his 62^nd birthday in 2025.

“A rooftop birthday shower in NYC to start the day, and the love of family and friends to carry me through,” he wrote in the caption. “At 62, I’ve learned the best things in life can’t be washed away…laughter, love, and gratitude. Thank you for every wish and every year. I don’t take a single drop for granted.”

Two years prior, John celebrated his 60^th birthday with another outdoor shower shot, thus kicking off the tradition. The star’s wife, Caitlin McHugh Stamos, shared further insight on social media into how he spent his special day.

“This guy didn’t want a birthday celebration this year, so we’re doing multiple days celebrating!” she wrote on Instagram. “Started with Willy Wonka at @cosm, continuing today and beyond! How could we not celebrate the birth of one of Earth’s best humans!”

John has been a Hollywood staple since he stole hearts in General Hospital in the ’80s, and then became a superstar thanks to his role in the hit sitcom Full House. 

Despite being in his 60s, John shared with Us Weekly that he felt younger than ever thanks to several lifestyle changes.

“I am getting old, although I don’t feel it. I take care of myself. I stopped drinking 10 years ago. That’s why I’m alive. I never would have met my wife if I was still drinking,” he told the publication.

“I’m happy where I’m at in my career, but I think I would be a lot further along if I’d stopped sooner. I got the job done, but I could have done it better, and I could have been more connected. Getting married and having a child, that’s kept me young and kept me alive. I think that’s helped with my longevity.” John and Caitlin welcomed their son, Billy, in 2018.
