Justin Beiber strips to his boxers on stage

Justin beiber did the unthinkable at Fashion rocks 201 on Tuesday, the star singer stunned the crowd when he stripped to his calvin klein boxers while introducing Rita Ora on stage.

Beiber who teamed up with model, Lara stone to introduce Ora, was booed by the crowd as he made his way to the stage to speak and in a rather witty move to make the crowd stop the 'booeing', Beiber sent the ladies sprawling by stripping to his boxers. See more pics below........
