After Kim Kardashian's daring nude GQ cover, sister Kendall Jenner has followed in her footsteps!

The Keeping Up With The Kardashians star posed completely naked for a new portrait by photographer Russell James. Older sister Kourtney Kardashian posted the nude black-and-white picture of the sultry 18-year-old on Instagram.

"Saturday muse," she captioned the photo of the nude-teen.

Jenner in the picture sported wet, messy hair. She sits down for the sexy pose and reveals the side of her breast, while barely covering her buttocks. The post has earned more than 436,000 likes and generated more than 7000 comments.

But Kendall's fans are outraged by her bold nude photoshoot.

"She's too young!" commented one follower.

Another outraged fan said, "Did you mom make you post this picture if your 18 yrs old sister ?? Would you post this picture of your daughter ? Just asking"

Another said, "Hmm i wonder what Bruce Jenner said about this!! Let me guess "makes me sick to my stomach"

The reality-television star turned model recently dropped her last name to distinguish her TV career from her fashion career, Radar Online reported.

Kendall apparently believes the Kardashian/Jenner name has negative roots, and she does not want it to affect future fashion shoots and shows.
