Kendall Jenner is giving sister Kim Kardashian some big booty competition!
The "Keeping Up With the Kardashians" star took to Instagram to share a snapshot of her perky derriere, where she's showcasing her curves in a pair of white Calvin Klein underwear and some low-slung jeans.
"#DenimDay," she captioned the pic of her bum on National Denim Day.
The 19-year-old beauty also gives CK some love in the 95th issue of V Magazine, as she lounges in a chair, wearing only a pair of shorts, a Calvin Klein bra and high heels.
Inside the mag, she opens up about her difficult time breaking into the modeling world and how she feels seeing herself in her first major campaign for Calvin Klein Jeans titled #myclavins.
"You have no idea how many doors closed on me and how many adults were either initially reluctant to take a chance working with me or who outright laughed at me behind my back," she tells the mag. "It was kind of hard because all I was doing was going on go-sees, trying my best to break into this business as a teenager."
"I am so grateful to Marc Jacobs, Riccardo Tisci, Karl Lagerfeld, and Katie Grand, who took a chance on me that first season and gave me an opportunity," she adds. "My parents taught me that work ethic is one of the most important keys in life, and I believe it."
While Kendall has modeled on the runways of Paris and New York, seeing herself in a major campaign is a big milestone in her flourishing fashion career.
"This will be my first billboard on Sunset, which I'm ecstatic about," she gushes. "It's really humbling, and honestly, I am a pretty shy person, but being part of the Calvin campaign and seeing myself up there will be a dream come true."
"I might have to eat every night at the Chateau Marmont with that hanging over my shoulder. 'Oh yeah, that little thing? I didn't notice!'"
We have a feeling Kendall is just getting started!
