Kim Kardashian admits she was "mortified" when she heard her mom Kris Jenner having sex with her boyfriend Corey Gamble.
In this exclusive bonus clip from Sunday's Keeping Up With the Kardashians season 11 premiere episode, Kim talks to Kourtney Kardashian and Khloe Kardashian about her mom's relationship.
The trio sits down after Kourtney and Khloe went wine tasting with Kris and Corey.
"Mom and Corey were... I had to turn my back to them," Khloe says. "They were like two teenagers. Mom was like laying in his lap and they were like making out, she was like holding his face. It was so uncomfortable. I feel like they're like balls to the walls. You heard how comfortable they were banging on the bed."
"What?" Kourtney asks.
"When they first started dating I was like sleeping right below them," Kim explains. "It was pretty loud and I was just like mortified."
