Calvin Klein Becomes A Belieber

Justin Bieber stars in the Spring 2015 ad campaign for the U.S. fashion house’s jean and underwear collections. The bad boy superstar can be seen the kicking off 2015 in his underwear! The pop star teased his new Calvin Klein modeling gig on social media, sharing racy photos from the upcoming campaign, some of which show Bieber wearing nothing but his tight white boxer briefs and his washboard abs.

Calvin Klein dropped a new, six-second ad on its Twitter Tuesday, and it features none other than Justin Bieber wearing only pants (and his Calvins). The shirtless Bieber shows off his drumming skills in the short ad, but you never see his face!

The Canadian superstar is known for walking around in his underwear and now he is getting money out of it. Modelling alongside Dutch model Lara Stone, shot by Mert Alas and Marcus Piggott, the video was shot by Johan Reneck. Calvin Klein is known for racy ads and this definitely will leave some Beliebers (and their moms) needing a cold shower!

The 20-year-old "Home to Mama" singer cosies up to a faceless model at the last second while showing off his Calvin Klein undies in the video. The brand formerly announced that its Fall 2014 Calvin Klein Jeans and Calvin Klein Underwear would be brought together in one global advertising campaign featuring supermodel Lara Stone and male model Matt Terry. There wasn't any mention of Bieber at the time, but it looks like it didn't need to because we get to see him now in all his glory!

Fun Fact: Bieber was ranked #1 most-tweeted-about artist for 2014.
