Kim Kardashian has accused Kris Jenner of being a 'bad mother' for allowing her youngest daughter Khloe to keep in touch with her troubled ex-husband Lamar Odom.

Speaking in an upcoming episode of Keeping Up With The Kardashians Kris' middle daughter sits down to tell her to stop allowing Khloe to communicate with her ex who is believed to have cheated on her while they were married.

"You just have a sentimental thing with Lamar, and at some point, you have to get over it," Kim tells Kris.

"Okay, but you weren't going to give me the benefit of the doubt. I always want what's best for my daughters," the 60-year-old replies.

To which Kim hits back: "Her talking to Lamar and you saying Lamar deserves a second chance - that is so wrong, and that's being a bad mother."

"All right, what else do you want to call me? I would never speak to somebody the way you speak to anybody. Your words hurt," Kris replied.

Kim continued: "Even for them to speak, it's not healthy for Khloe. She's moved on, and now you are solely pulling her back."
