Justin Bieber Strips Off His Clothes After Audience Boos

See Bieber in nothing but his underwear at Fashion Rocks event.

After being booed by the crowd at the Barclays Center in Brooklyn, New York, the pop singer stripped to his boxers and socks, revealing his Calvin Klein underwear. It seemed like an attempt to silence the aggravated crowd.

“I actually don’t feel comfortable unless I’m in my Calvin’s. So what’s up?” Bieber said to co-presenter and model Lara Stone.

After the NYC Fashion Week event, Bieber took to Twitter to explain his actions.

"Grandma always said kill 'em with kindness...and then strip on live national tv. Lol," he wrote, along with a Vine video of him stripping. "Good times tonight. Thanks for having me tonight #FashionRocks. #mycalvins :)"

Even his co-host thought the move was funny.

"Thanks for that @justinbieber ???? @calvinklein @fashionrockslive #dope #nycalvins," Stone wrote on Instagram.
