"I want to be with you in #mycalvins," she captioned a racy Instagram video montage that includes close-up shots of her features on Tuesday. "My new Spring 2016 @calvinklein campaign... What do you do in yours?"
The post was followed up with a snap of Jenner from the campaign, in which the supermodel leans back on a stool and shows off her toned tummy while rocking a sports bra and underwear from the popular brand.
"I pose in #mycalvins," she wrote on Wednesday. "What do you do in yours? Here's my Spring 2016 @calvinklein campaign shot by Tyrone Lebon."
Prior to the exciting announcement, Jenner made headlines one day earlier with a video posted to Vogue magazine's Instagram.
In the short clip, Jenner shows off her twerking skills in a beautiful designer gown outside of Chanel's Haute Couture Spring-Summer 2016 runway show in Paris alongside her close pals, sisters Gigi and Bella Hadid. See it go down in the video below.
