Justin Bieber, Calvin Klein Underwear PHOTOS: Following In Footsteps Of Mark 'Marky-Mark' Wahlberg To Model For Designer?

Is Justin Bieber the next face of Calvin Klein? Judging by his latest spate of Instagram photos, that may be a possibility.

This week and for the past few months, the Beebs has been posting photos of himself shirtless, muscular and rocking his Calvin Klein underwear.  And an unnamed source at the design house reportedly says Beiber has indeed shot for Calvin Klein, with the results possibly released later this year.

In the past week alone, Bieber has posted at least three shots of his CK undies, and one of model Ashley Moore donning a similar pair.

If Bieber is indeed modeling for Calvin Klein, it would not be a surprise - the pop idol has made no secret of his love for the brand. Rumors also surfaced in April that he would appear in an ad campaign with Keeping Up With The Kardashians star Kendall Jenner.

In the spring, she too took to her Instagram account sporting CK tops and bottoms. The caption read, ""Just going to hang out in #myCalvins all day! Thank-you Calvin Klein for my little gifts."

As the next face of the brand, he would be following in the footsteps of actor Mark Wahlberg - then a rapper nicknamed Marky Mark.

Wahlberg, much like Bieber, had his share of run-ins with the law in his youth. He was jailed for attempted murder for two years for his role in a series of hate crimes.

Neither Calvin Klein nor publicists for Bieber have commented on the rumors.
