She's following in her sister's footsteps!

Kendall Jenner has joined the modeling world with ease and has taken things one step further as she posed nude for the cameras.

"Saturday muse. @nomadrj," her sister Kourtney Kardashian posted to her Instagram account yesterday, showing the 18-year-old wearing nothing at all while rocking some wet hair.

The photo was taken by Russell James, who's known for his infamous nipple pic of Kendall on her 18th birthday. Rumor has it that the photo will make his upcoming book, Angels, which is due later this month.

Looks like you just got one upped, Kim!
