A number of female celebrities ring in their birthdays by sharing photos in their birthday suits, so John Stamos decided to give his counterparts a run for their money by posing for one in his own. The Full House star turned 54 years old on 19 August, and on the occasion treated his fans to a very cheeky picture on his Instagram account.

Stamos shared a photo in which he poses butt-naked under an outdoor shower with the plants in the area doing little to cover up his derriere. "#54 and clean. Thanks for the birthday wishes!" the Scream Queen actor captioned the post.

Fans of the birthday boy were more than happy with the naughty picture, with one thanking him for the treat. "Wow you gave me a present on your birthday," one comment read.

The nudie followed a considerably tamer yet adorable throwback photo of Stamos as a young boy. "It's a wonder just how much of life sits before me eagerly (almost impatiently) waiting to reveal it's gentle, imperfect, often unimaginable beauty," he captioned the 20 August post. "When I've been willing to suspend my judgment, hold my criticism, proactively find the positive, and most importantly embrace wonder, I've found authentic happiness.

"To stumble safely this far together is a real wonder. Thank you for the lovely birthday wishes. Sending you much, much love!" he added.

The Grandfathered actor spent his birthday with former Full House co-stars Lori Loughlin and Dave Coulier at a Cinespia screening at Hollywood Forever Cemetery.

Earlier that day, he also took time to pamper himself and show exactly why he looks great for his age. In his Instagram story, Stamos shared an image of him enjoying a "Birthday facial".

While he has made it known that he likes indulging in skincare rituals, he once joked on Late Night with Seth Meyers that his looks were courtesy a deal with the devil.

"Hey little John, you will have a fantastic life as long as you make sure you do one thing," Stamos began in a "message to his younger self".

"Now on your eighteenth birthday the Prince of Darkness, Satan, will offer you eternal youth in exchange for your soul. Little John, I'm telling you right now... you take that deal, son."
