James Franco bared his butt in front of a packed house while performing at Broadway Bares, an annual cabaret fundraising event put on by Broadway Cares.

James Franco Performs With Bianca Del Rio

Franco surprised the over 1,000 members of the audience Sunday night when he appeared onstage alongside drag queen Bianca Del Rio, winner of RuPaul's Drag Race. The two performed a skit in which Franco tried to gain entry into a nightclub.

“Don’t you know who I am?” Franco asked. “I’m James Franco… I’ve got like 2 million followers on Instagram, I do topless selfies,” Franco added, poking fun at his infamous nearly naked Instagram selfies.

The bouncer refused Franco entry, and called Rio out on stage to perform a “full body search” on Franco.

“And, just so you know Franco, this is going to be as painful as you hosting the Oscars,” Rio quipped before puling down Franco’s pants, eliciting wild cheers from the audience.

Broadway Bares: Rock Hard! was choreographed by Broadway director Jerry Mitchell and featured cast members from a large array of Broadway musicals. Performers are known to strip down for the event, which is full of performances and celebrity guests. This year’s Broadway guests included Alan Cumming, currently starring in Cabaret, Rocky’s Andy Karl, Patrick Page and Alex Minsky of Casa Valentina and Matilda The Musical’s Christopher Sieber and Lesli Margherita.

Franco later posted a photo of the event to Instagram, encouraging his fans to support Broadway Bares.
