The 38-year-old showed off her birthday suit in a shot by photographer Mike Rosenthal, simply captioning the image, "mother nature." Needless to say, fans were impressed by the brunette beauty's flawless figure — especially given the fact that she's a mother-of-three.
"You are perfection!" one follower wrote, while another said, "Best looking Kardashian...stay natural."
Well, Kourt isn't all natural. The reality star has always been open and honest about the boob job she got when she was 22. "It was so dumb ... I just got the idea in my head one day, and that was that. There was no talking me out of it," she previously said about the surgery.
The oldest Kardashian kid has been all about the naked pics recently. For her birthday on April 18, Kourtney posted another photograph by Mike in which she whips her hair back while standing in a pool. A hint of nipple made it past the Instagram censors that time.
The fashionista also has a nude portrait of herself from a pregnancy photoshoot hanging in her home. The stunning shot was taken while the reality star was expecting her third child, Reign, in 2014.
"To me, nudity is not something to be ashamed of," Kourtney told Dujour.com. "I’m not embarrassed of my body. I’m at my best when I’m pregnant. It’s such an amazing feeling, the transformation that your body goes through. There’s something about that that’s so empowering and beautiful and I just really embrace it."
