Pop star Justin Bieber strips down for Calvin Klein's newest underwear campaign

Pop star Justin Bieber shows off his toned physique in Calvin Klein's newest ads for their underwear and jean lines.

 

The platinum singer provides the soundtrack for the commercial advertisements by playing a drum solo and speaks only two words: "My Calvins."

 

Dutch supermodel Lara Stone is paired with Bieber for the black and white campaign shot by fashion photographers Mert Alas and Marcus Piggott .

 

The Canadian said being a part of the campaign is the beginning of a very exciting year.

 

"To be the next Calvin Klein underwear jeans model for me was the next step really. I've been wearing Calvin Klein underwear for years. Kind of in hopes of being one day the Calvin Klein model, but never really like thinking it would come to reality. And now that it's here it's really a dream come true," said Bieber.

 

Bieber said preparing for the shoot was all about mind and body.

 

"I'd prepared myself for this shoot by just working out a lot. And just getting my mind ready, being healthy. It's always great to ear healthy and drink a lot of water."

 

Bieber and Stone are now a part of an exclusive club of CK underwear models that includes Mark "Marky-Mark" Wahlberg and Kate Moss.

 

The fashion brand will take advantage of Bieber's social media reach by asking fans to post selfies of themselves in CK clothes with the hashtag #mycalvins.  — Reuters
