Justin Bieber, Kendall Jenner, More Strip Off for Calvin Klein Ad Teaser: Pics

Whoa steady, Justin! Justin Bieber's near-naked body is part of a very eye-catching teaser for Calvin Klein's new advertising campaign, in which stars reveal what it is they do in their Calvins. 

But don't panic! If the image of Bieber, laid out on his fresh white sheets, his hand, delicately draped over his, well … crotch, is making your mind wander, fear not. All the 21-year-old singer does in his Calvins is dream!

This photo alone might be enough to make it into your dreams — but wait, there's more! Bieber's in good company with his barely there Calvin revelations. Kendall Jenner also stripped down to her undies, images of which can be seen in a video montage of pictures she shared via her Instagram on Tuesday, January 26. And a host of others including FKA twigs, Kendrick Lamar and Fetty Wap shared details of their secrets in a second video, posted on Calvin Klein's official Instagram.
