Kendall Jenner shows off more than just her runway skills during Fashion Week

Kim Kardashian's little sis showed off more than just her runway skills over the weekend.

While Kendall Jenner is making a name of her own for strutting her stuff at the Diane von Furstenberg show during New York Fashion, she's also following in her big sisters' footsteps.

Sister Kourtney shared a picture of Kendall's nude portrait for photographer Russell James on Instagram. "Saturday muse," she captioned the photo of the 18-year-old's sultry pose.

Big sisters Kim, Khloe and Kourtney have all posed nude as well. Most recently, Kim made a splash with her nude photo shoot for GQ magazine.

The reality star turned model recently dropped her last name in order to distinguish her modeling career from her TV personality.

"I did it last year at all the castings, too!" she told Us Weekly. "I only go by my first name."
