The most recent: Kourtney stripped down for arguably her sexiest photo shoot yet, with fashion rag V magazine.
The 39-year-old reality star is a vision for photographer Greg Swales, posing in a latex trench coat, a leather corset and nothing else.
You know that her ex-boyfriend Scott Disick must be jealous as all hell.
In the shoot, she's rocking some Kylie Cosmetics, the wildly popular makeup line from younger half-sister Kylie Jenner. She even collaborated on some new products for the line and appeared in a recent campaign photo alongside Kylie.
"I think this shoot, using my collab with Kylie, was the perfect situation to try some new stuff," she told V, hinting at the sexier and edgier direction of the shoot.
"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."
We love her no matter her style. See what we mean with her sexiest Instagrams, here.
