In the pictures, the 35-year-old mother of two proudly shows off her famous curves in looks styled by Monica Rose, reported Us magazine.
One shot features the 'Kourtney & Khloe Take the Hamptons' star in a soaking wet, see-through white dress, revealing her blossoming baby bump.
Another photo shows the sultry brunette cradling her belly while draped in a satiny white robe. And in a third picture, she poses in nothing but a feathered bib.
"I had done a nude shoot when I was pregnant with Mason, really last minute just for myself, and I love it. To me, nudity is not something to be ashamed of," she said about the shoot.
