Seems the Kardashians family has been going butt naked for the camera lens lately. Just recently, Kim Kardarshian West took it all off for British GQ magazine, now Kendall Jenner, Kim’s kid sister followed sooth.

Kourtney Kardashian posted the pic above on her Instagram page last night, captioning it “Saturday muse.” The photo shows the 18-year-old reality TV star/model posing in absolutely nothing at all while rocking some wet hair. The picture was taken by photographer Russell James, who also shot that now infamous nipple photo Kendall posted on her 18th birthday.
