Kourtney Kardashian has nothing to hide!
The 38-year-old reality star strips down to her birthday suit for a photo shoot in a new promo forSunday's Keeping Up With the Kardashians.
"Are you naked under this?" Kylie Jenner asks her sister just before she disrobes. "So, you really are getting naked?"
"Yes!" Kourtney says. "What do you mean?"
The mother of three then ditches her robe for the photo shoot, as sisters Kim and Khloe cheer her on.
"I honestly was worried about you after [you had] Penelope. I did think, like, 'She's gone,'" Khloe tells Kourtney. "Now she's YOLO-ing it up. F**king bomb-ass body, naked in the pool. Your sisters should be afraid of you."
Kourtney definitely isn't shy. A source told ET earlier this week that she's been "having a lot of fun" with 24-year-old model Younes Bendjima.
"They are having a lot of fun together and it’s very casual," the source explained. "They met through mutual friends in Los Angeles.”
As for what Kourtney's ex, Scott Disick, thinks of her new romance, the source says that "he knows it’s time to move on, but it’s still hard."
