Justin Bieber Stripped Down to Just His Boxers Calvin Klein on Fashion Rocks Stage

 Justin Bieber flexes his muscles while stripping down to just his Calvin Klein boxer briefs on stage at 2014 Fashion Rocks held at the Barclays Center of Brooklyn on Tuesday (September 9) in New York City.

Justin Bieber, 20, just upped the hotness bigtime at Fashion Rocks. He came out to introduce a stellar performance by Rita Ora with model Lara Stone — but totally stole the show! We loved the blue blazer he was rocking, but he didn’t keep it on long. Instead, he actually threw it on the floor, with the rest of his clothes. Yes, he stripped down to his Calvin Klein undies!
