Justin Bieber kicked off his 2015 in a sexy new ad campaign for Calvin Klein.

A shirtless Bieber stars in a short black-and-white video teaser posted Tuesday on the Calvin Klein Instagram. The camera never shows his face as he's filmed from behind, playing his drumkit. The video then cuts to him pulling a blond model close to his bare chest for an intimate kiss.

"Drum roll... #mycalvins," Calvin Klein captioned the six-second video.

Bieber confirmed the new gig on his own Instagram with a series of photos from the campaign. Along with a solo shot, he also poses with model Lara Stone wrapped around his bare chest.

He also seems to want to turn a new leaf in the new year after his many legal troubles in 2014.  "This is just the start of the year #mycalvins #beallyoucanbe #learnfromyourfaults #risetosuccess #dontbeashamedredeem #thebestisyet2come," he captioned another photo.

The 20-year-old singer is frequently seen wearing his own Calvins, protruding out the top of his sagging pants. He proudly stripped down to his pair of Power Red Micro boxer briefs while presenting at Fashion Rocks 2014 in September.

Bieber also attended a photo shoot for a Calvin Klein fashion campaign in April, according to HollywoodLife.com. "He's here for a Calvin Klein photo shoot and Kendall [Jenner] is here too," a source said at the time.

Kellan Lutz previously served as the face and, of course, impressive body of the Calvin Klein underwear ad campaign. Actor Mark Wahlberg was the most notable celebrity to don the briefs in the early 1990s, his steamiest ads coming alongside model Kate Moss.
