Justin Bieber takes it (almost) all off in new ads for Calvin Klein

Oh baby! Justin Bieber is all grown up, and nothing comes between him and his Calvins.

On Tuesday, the 20-year-old pop star appeared in black-and-white images posted on on Facebook and Instagram featuring him as the new model for Calvin Klein underwear and jeans.

And whatever you may think of Bieber and his music, the fact is that he looks pretty darn good.

While the Facebook photos show the singer standing alone, he's posed with model Lara Stone in the Instagram picture — and if that pairing seems familiar, it's no déjà vu. Stone and Bieber appeared on September's "Fashion Rocks" TV special, where he performed and stripped down to his skivvies.

But while that stunt was greeted with boos, the new images are blowing Beliebers' minds. In just over 12 hours the Facebook pictures had received nearly 800,000 likes. 

In addition to the still images, Calvin Klein also put up a brief video on Instagram of Bieber getting up close and personal with Stone.

Bieber joins a long tradition of stars making racy ads to promote the Calvin Klein brand. Brooke Shields made headlines in 1981, when she was just 16, for saying in an ad that "nothing" came between her and her Calvins; Mark Wahlberg posed in 1992; in 2011 "Twilight" actor Kellan Lutz also struck a pose.

So are there more photos on the way? We'll have to wait and see: Bieber's comment on his Facebook post said simply, "It begins." Sounds like a promise.
