Move over Beach Boys -- John Stamos' "beach buns" were the true headliner at a Sunday night concert at the NYCB Theater in Westbury, New York.
The Fuller House stud was jamming on stage with the musical icons, performing their 1964 hit "Fun, Fun, Fun," when he realized his pants were split.
Turning around to check out the rip, the 53-year-old actor and musician then expertly went on with the show, seemingly unfazed by the wardrobe malfunction.
He later took to Instagram to share a clip of the moment he realized something wasn't right.
"...and then, somewhere towards the end of Fun, Fun, Fun - I felt a slight breeze in the buttocks area.... #SplitPants #TheBeachBUNS#showmustgoon," he captioned the video.
The post was welcomed by fans, who praised the Scream Queens hunk for his great form.
"Great butt and looks like you wore matching underneath 😝," commented one Instagram user.
"At least you hv on underwear unlike when Lenny Kravitz split his pant! Oy vey!!! 😂😂😂," wrote another.
As for the lucky lady who gets an all-access pass to his "beach buns," Stamos recently dished to ET about his gorgeous girlfriend, Caitlin McHugh.
