Justin Bieber Strips at Fashion Rocks and Gets Booed

Justin Bieber awkwardly stripped down to his Calvin Klien underwear during a live CBS telecast of the event "Fashion Rocks" and got annoyed boos from the crowd.

Accompanied by model Lara Stone, Bieber walked on stage and the audience was already hostile...boos are heard as soon as he appeared. But they increased when he abruptly undressed. There definitely ARE some cheers in there but the booeing stands out more...
