Holy Smokes! Kourtney Kardashian Strips Completely Naked For V Magazine

Kourtney Kardashian celebrated her 39th birthday on April 18, but you would never guess it by looking at her steamy new photo shoot in V magazine.

"I think this shoot, using my collab with Kylie, was the perfect situation to try some new stuff," Kourtney told the magazine. "I've lately been in a mood to try more things with makeup and hair, and I personally have even more fun with it when I have a reason." Turn up the AC, and check out Kourtney's sexy photos ahead.
