Kourtney Kardashian Nude In Behind-The-Scenes KWUTK Clip — See Scott Disick’s Reaction!

Kourtney Kardashian already bared it all for her nude (and pregnant!) photo shoot for DuJour magazine, but now the mother-of-three is baring it again behind-the-scenes.

In a clip for Sunday’s Keeping Up With the Kardashians, fans follow Kourtney, accompanied by sister Kim Kardashian and Scott Disick, as she strips down for DuJour.

Kourtney posed for the magazine which released the photos back in December, but her day in the studio while still pregnant with her third child, Reign Aston Disick, will finally air on KUWTK now. Of course, Reign was born in December.

During her shoot, Kim Kardashian watches from behind the camera, calling the shoot “so pretty.”

“Oh this is an angry shoot? You’ve got a child in there for crying out loud,” he jokes.

“I didn’t even know you were this pretty,” he goes on. “I learn something new every day.” Oh, Scott!

He also says she looks “well-sculpted downstairs” and says this makes him know he has more than one talent.

"She does look quite amazing, I mean she's really got a glow to her, so I'm pretty proud of her," Scott added.

“We were shooting for our show, and everyone on our camera crew was like, ‘You are so comfortable just walking around naked and pregnant!’” she told DuJour. “And Scott, who stopped by with Kim said the same thing to me, like ‘How are you fine just standing there like naked with all these people around?!’”
