Have mercy!

John Stamos might be 62, but that doesn't mean the Full House heartthrob has to refrain from sharing steamy photos. In a recent post honoring his birthday, the actor shared a snap from his time enjoying an outdoor shower in nothing but a pair of Calvin Kleins, showing that he's still got it.

"A rooftop birthday shower in NYC to start the day, and the love of family and friends to carry me through," he captioned the Aug. 19 post. "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."

Adding a play on words to go along with the soaked selfie, he continued, "I don’t take a single drop for granted."

Singer Richard Marx, 61, shouted out John's confidence and good looks, commenting, "Look at you up there making folks thirsty! Happy birthday bro!"

Rita Wilson, 68, also complimented the Beach Boys singer, writing, "I love this. A ny rooftop birthday shower!"

Even his TV "niece" joined in to wish her Uncle Jesse well, with Candace Cameron Bure commenting, "Happy birthday uncle J." 

Of course, plenty of fans felt thankful they had the chance to see the photo. As one put it, "Still A HOTTIE."

So, what's kept John so youthful at this stage of life?

"I don’t do a lot. I wash my face," he told Us Weekly in an interview published Aug. 19. "I work out three or four times a week."

While John—who shares son Billy, 7, with wife Caitlin McHugh—also noted the importance of "good sleep," he added that it's his family that has helped to keep his energy up, sharing, "Having a young son helps."

"I am getting old, although I don’t feel it," he explained. "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 continued, "Getting married and having a child, that’s kept me young and kept me alive. I think that’s helped with my longevity."
