John Stamos and Glen Powell Strip Down in Eye-Popping Birthday Tribute!

John Stamos celebrated Glen Powell’s birthday with a cheeky Instagram tribute that left fans exclaiming, “Have mercy.”

The former “Scream Queens” star shared a series of playful photos on Instagram Tuesday to mark Powell’s 37th birthday.

“Happy Birthday @glenpowell, the man who’s seen me naked more times than I’d like to admit,” wrote Stamos, 62, in the caption of his post.

“Love you buddy! Steam room date soon? xo JS,” he added.

In the first image of the Instagram carousel, Stamos and Powell can be seen walking down a street barefoot, using a skateboard and shopping bags to cover themselves.

In another photo, they are joined by Taylor Lautner, with the three seen grinning in showers.

The series of photos wraps up with Stamos and Powell in a steam room, first draped in towels and then wearing black shorts.

“The best,” commented Lautner, 33, on the post.

Enthusiastic fans commented on the post, with one fan remarking that Stamos’ post was “more like a happy birthday to us” and several quoting his iconic “Fuller House” character, Jesse Katsopolis, saying, “Have mercy.”

Stamos, known for his role on “Grandfathered,” often celebrates his own birthday in a similarly revealing manner.

On his 54th birthday in 2017, Stamos posted a cheeky snapshot of himself showering outdoors surrounded by palm fronds.

He captioned it “54 and clean.”

For his 60th birthday, Stamos shared another suggestive shower photo taken by his wife, Caitlin McHugh.

Titled “The other side of 60,” the photo shows Stamos modestly covering himself with one hand.

Stamos and McHugh, who is 39, tied the knot in February 2018 and are parents to a 7-year-old son named Billy.
