The reality star-turned-model of the moment, 19, struts her stuff (and strips down) in a black and white video, shot this past December in NYC, to promote the beauty brand's latest product, the Little Black Primer—a before-and-after mascara treatment for your lashes.
Taken on the set of the shoot, this exclusive behind-the-scenes photo at the top of the page flaunts Jenner's complete ensemble. The Instagram queen works a chic blazer, loose tanks, liquid leggings, and peep-toe ankle booties on the set.
But the clothes didn't last for long! In the video, between shots of Jenner on a checkered set, then in a glam mansion, the camera zooms in on the Kardashian-Jenner clan's model member, close-up and topless.
The Estee Lauder Little Black Primer ($24) is available to shop on Esteelauder.com now.
