How to avoid a booing crowd? Strip down to your undies. That's what pop star Justin Bieber believes in. The 20-year-old was booed when he made an appearance at the Fashion Rocks 2014 event in Brooklyn, New York on Tuesday night. But the unwary welcome by crowd did not dampen his spirits and the "Baby" singer stripped down to his undies right there on the stage!

"I actually don't feel comfortable unless I'm in my Calvins," Bieber said before undressing. Bieber was introducing Rita Ora's performance alongside model Lara Stone when the incident took place and the crowd started booing him.

The on and off boyfriend of Selena Gomez first took off his smart blue blazer, followed by unbuttoning his pants and then he even removed his socks and shoes without any hesitation. The singer even took off his black tight t-shirt and showed off his toned and tattooed body on stage. He stood there in just his undies looking very much like a Calvin Klein model. Justin wore dark red and black boxer shorts from the brand. The singer proudly showed off his body to the audience who was now cheering for him.

"Is that better?" asked Bieber to the crowd at the charity event which had the presence of some of the world's top fashion designers and Hollywood celebrities including Jennifer Aniston. Singer Rita Ora gave her live performance at the event, which was telecast on national television.

"Good times tonight. Thanks for having me tonight #FashionRocks. #mycalvins:)," Tweeted Bieber after the event. The singer also re-tweetd a fan's Vine video of his striptease act.

"Grandma always said kill 'em with kindness...and then strip on live national tv. Lol," he joked. Check out his Tweets below.
