Justin Bieber was heavily booed by the audience at the Barclays Center on Tuesday night in Brooklyn, New York. He entered the stage to introduce singer Rita Ora, and once the crowd booed loudly, he stripped down to his boxers and socks.
"I actually don't feel comfortable unless I'm in my Calvin's. So, what's up? Is that cool?" Bieber said to his co-presenter, model Lara Stone.
