Bieber Crashes 'Fashion Rocks' Charity, Strips on Stage

Boos turned to boxer briefs last night at Brooklyn's Barclay Center when former teeny-bop batboy Justin Bieber made an unannounced appearance at the annual "Fashion Rocks" charity event and gave a semi-appreciative audience an impromptu striptease.

Justin Bieber made a surprise appearance at "Fashion Rocks" in Brooklyn, Tuesday night, showing up unannounced to introduce Rita Ora's performance. Upon entering the stage, the Biebs was greeted with boos from the audience. In an attempt to give the people what they want, he showed the crowd the only thing about him that looks good these days - his ripped bod.

As reported by E online, upon hearing the jeers, Bieber unbuttoned his blue blazer, kicked off his shoes, dropped his pants and ripped off his black tank top, ending up on stage in nothing but his tight black Calvin Klein boxers. "Is that better?" he asked the crowd.

Apparently, yes.

When the burlesque began, the booing stopped.

Rita Ora then performed with the corresponding Calvin Klein fashion show.

He later tweeted "Grandma always said kill 'em with kindness...and then strip on live national tv. Lol."
