Kendall Jenner Strips Down For New Calvin Klein Campaign

Kendall Jenner proves that she really is the hardest to keep up with. Having starred as Estée Lauder's muse for their latest fragrance and closing the show for Chanel's fall 2015 couture show as Karl Legerfeld's bride, she's now also the face of Calvin Klein Underwear's latest campaign. This is the second time Jenner has fronted the iconic brand, with the first being Calvin Klein Jeans.

Together with models of the moment Joan Smalls, Isabeli Fontana and Edita Vilkeviciute, the quartet pose for "The Original Sexy" in what seems to be Calvin Klein's raciest ad yet. Jenner herself is seen wearing nothing but a see-through thong, showing delectable derrière, and another in just a bra.

Photographed by fashion photographer Mikael Jansson, the campaign aims to bring back their signature brand of sex appeal. "Calvin Klein originated sexy and we're going to reclaim, re-imagine and re-image it," said Melisa Goldie, Chief Marketing Officer of Calvin Klein, "We're bringing together a powerful mix of women from all over the world to celebrate our heritage as a leader in the intimates category."

With that said, we're definitely getting ourselves a pair of Calvins. See the rest of the shots of Jenner, Smalls, Fontana and Vilkeviciute:
