Social Muse: Kourtney Kardashian Shares Nude Image of Kendall

On the same day she made her Spring 2015 debut at NYFW, Kendall Jenner got a little social media love from big sister Kourtney Kardashian, who posted a stunning nude portrait of her little sister on her Instagram account. "Saturday muse," Kardashian wrote of the image, photographed by Russell James. We're sure it was just the right amount of encouragement Jenner needed as she entered into the fashion month fray. In fact, Jenner continued her naked streak this morning, walking Tommy Hilfiger in a teeny bikini and sheer slip.
