Justin Bieber Gets Naked at ‘Fashion Rocks’; Crowd Boos

Fashion Rocks was all about music and clothes — or, in Justin Bieber‘s case, lack thereof.

During the CBS live telecast on Tuesday night, the singer hit the Barclays Center stage with model Lara Stone to present performer Rita Ora and the corresponding Calvin Klein fashion show.

Though he was welcomed by an overwhelming slew of boos from the arena’s audience, he went on to shed his blue blazer, black top and pants, ending up only in a pair of black and red boxers, and noting that he’s only comfortable in his “Calvins.” Once he started flexing, the high-pitched screams drowned out the haters.

He later tweeted about nearly baring it all:

Grandma always said kill ’em with kindness … and then strip on live national tv. Lol. https://t.co/bKbeDJVsqJ
