Perez Parties With Stamos and the Boys

Perez Hilton, the self-proclaimed "Queen of All Media" and the man behind PerezHilton.com, partied on stage with good friend John Stamos as he jammed with the Beach Boys at a concert last night.

Perez, currently filming a reality show, was surprised when Stamos (playing guitar) pulled him up on stage to sing a song with the band. Only one problem: he didn't quite know the words to "Fun Fun Fun."

"I was kinda nervous because I didn't know any lyrics, except the chorus," he told TMZ. "But I just sang my little heart out and had fun."
