Kourtney Kardashian ditches her clothes in a provocative photo shoot. The heavily-pregnant star shows off her curves for DuJour. One photo shows her wearing nothing but a feathered bib, another sees her donning an open white robe, and the other features her flaunting her body in a wet dress.

"I had done a nude shoot when I was pregnant with Mason, really last minute just for myself, and I love it," Kim Kardashian's older sister says. "This time, we were shooting for our show, and everyone on our camera crew was like, 'You are so comfortable just walking around naked and pregnant!' "

"To me, nudity is not something to be ashamed of," she explains. "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."

"But I would never say never to doing a nude shoot not pregnant," she adds. "What appeals to me is celebrating the shape of my body being pregnant and capturing that time in my life...It's a wonderful thing to be able to show my children these photographs one day and say, 'This was you inside.' "

Kourtney is currently expecting her third child with beau Scott Disick. The baby will join big brother Mason, 4, and sister Penelope, 2.
