John Stamos left fans swooning after sharing a revealing photo to mark his 62nd birthday, and they keep noticing the exact same thing.
The Full House star took to Instagram to post a picture of himself enjoying a rooftop shower in New York City, wearing only a pair of Calvin Klein underwear.
The image, which highlighted his toned abs and biceps, was enough to send social media into overdrive.
“Happy Birthday, Daddy!” one fan wrote in the comments. Another added, “dammmn thanks for posting this. So your bday gift is a gift to us. John A Very Happy Bday and many many more.”
And plenty of the actor's fans made an observation about his belly button, or apparently lack thereof.
One follower penned: "Happy birthday!!! Where is your belly button though?!?"
Another simply asked: "Where's your belly button?"
A third added: "Your mafic belly button has disappeared! Do you keep it in a jar? Happy birthday, Bada**!"
Fans weren't the only ones reacting to Stamos' birthday post. Several of his celebrity friends chimed in with their well-wishes.
Actress Rita Wilson commented, “I love this. A ny rooftop birthday shower!” while singer Richard Marx playfully pointed out the obvious, saying, “Look at you up there making folks thirsty! Happy birthday bro!”
Candace Cameron Bure, Stamos' co-star from Full House, also joined the celebrations with a simple yet affectionate message: “Happy birthday uncle J.”
Even Stamos' long-time friend and co-star, Dave Coulier, got in on the fun, sharing a series of photos from their years together, including a shirtless one of the two. “Happy birthday @johnstamos we’ve had Fun, Fun, Fun and so many laughs for so many years,” Coulier wrote. “I love you, my brother.”
Along with the playful photo, Stamos reflected on the past year in a heartfelt message. “A rooftop birthday shower in NYC to start the day, and the love of family and friends to carry me through,” he wrote. “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.”
Stamos also credited his wife, Caitlin McHugh, for keeping him youthful. The couple, who have been married for seven years, share a son, Billy, who is seven years old. In a past interview with Us Weekly, Stamos revealed that staying active and taking care of himself has helped him maintain his youthful appearance. "I work out three or four times a week," he said. "Good sleep helps, as does having a young son."
Reflecting on his journey, Stamos shared, "I stopped drinking 10 years ago. That’s why I’m alive. I never would have met my wife if I was still drinking. Getting married and having a child, that’s kept me young and kept me alive. I think that’s helped with my longevity."
Stamos' birthday post has certainly left an impression, with fans and friends alike celebrating the star’s timeless charm and vitality.
