John Stamos marked his 63rd birthday on Wednesday by sharing a shirtless, black-and-white mirror selfie on Instagram. The actor, known for his role as Uncle Jesse in "Full House," posted the image captioned simply "63." The photo appeared to show Stamos fresh out of the shower, with his hair slicked back.
His post garnered numerous comments from celebrity friends and fans. Kelly Rizzo, the widow of Stamos's late "Full House" co-star Bob Saget, wrote, "All I can think about is, ‘What would Bob say?’ right now 🥹🥹😂😂. Happy birthday, brother John. I love you! 🎂🎂🎂🎂🎂🎂🎂🎂🎂." Rita Wilson also commented, humorously questioning the age, "63???? You have the numbers flipped. 36!!"
This is not the first time Stamos has shared revealing photos on social media. In October 2025, he posted a series of shirtless pictures with his "Scream Queens" co-star Glen Powell to celebrate Powell's birthday. One caption read, "Happy birthday, @glenpowell, the man who’s seen me naked more times than I’d like to admit… Steam room date soon? xo JS." Among those photos were images of Stamos and Powell together in a steam room, with one showing them wearing only black shorts.
In August 2023, Stamos shared a similar shower photo to mark his 60th birthday, captioning it "The other side of 60." That image showed him shirtless in an outdoor shower, with the lower half of his body cropped out of the frame.
