We've never seen a fight this nasty between Kim Kardashian and Kris Jenner.
In this exclusive first look clip at Sunday's brand new episode of Keeping Up With the Kardashians, Kim and Kris continue to fight over the fact that Kris still talks to Khloe Kardashian's ex Lamar Odom.
"She's way out of line to speak to me like this," Kim says.
"I would never do anything to intentionally hurt my kids. I just love Lamar and she's gotta respect that too," Kris says.
Kim tells Kris, "You just have a sentimental thing with Lamar and at some point you have to get over it because what you did created a bigger stream of problems."
"I always want what's best for my daughter," Kris insists.
"Her talking to Lamar and you saying, 'Lamar deserves a second chance,' that is so wrong. That's being a bad mother!" Kim yells.
"I would never speak to somebody the way you speak to anybody," Kris tells Kim. "Your words hurt!"
Yikes! Watch the emotional clip to see is Kim and Kris can resolve their issues with each other.
