Have mercy! John Stamos celebrated turning 54 in his birthday suit, sharing a completely naked photo of himself in the shower on Saturday, August 19.

“#54 and clean. Thanks for the birthday wishes!” the Fuller House star wrote in a Instagram post of himself flashing his bare butt.

His caption could also be referring to his sobriety. As previously reported, Stamos, 54, checked himself into rehab after getting a DUI in June 2015. “I had such goodwill behind me,” he said during a September 2015 appearance on the Today show of his decision to seek treatment. “I really felt a lot of people were like, ‘Hey, John, go get healthy. We love you.’ It was time. I’m glad I did it.”

“I feel better than I’ve felt in a decade,” the Scream Queens hunk added of his post-rehab life. “I feel better than I’ve felt in a decade. I feel very, very good.”
