The announcement was made by the brand on -- you guessed it -- social media.
The ads were photographed by Alasdair McLellan and styled by Melanie Ward, and feature the 19-year-old model (who's posted plenty of pics in her Calvins) wearing streetwear-inspired looks from the limited edition, logo-driven collection, which will debut at Opening Ceremony.
Her makeup is kept to a minimum, save for a bold brow, and her hair is wet and slicked down.
The brunette beauty -- who's also fronted ad campaigns for Marc Jacobs, Estee Lauder and Karl Lagerfeld -- is joined by male model Simon Nessman for a few of the shots (but let's be honest, Kendall's the true star here).
"Modelling for Calvin Klein Jeans is really a dream come true," Jenner said in a statement. "I've grown up wearing the brand and seeing the iconic advertising in magazines and on billboards featuring some of the world's top supermodels. To now be a part of that legacy is truly an honour."
She also shared her excitement via Instagram.
Jenner joins Kate Moss (whom she posted a pic of prior to the announcement), Brooke Shields, Christy Turlington, and most recently, Justin Bieber and Lara Stone as the face of the brand. Now all that's left is a sexy snap a la Kate Moss and Marky Mark with Bieber (after all, they did look pretty cute together in Vogue!)
The collection will be available to shop at Opening Ceremony on April 15 and on calvinklein.com on May 15.
