Things are getting heated over at the Kardashian-Jenner household! In a preview clip of the upcoming season 12 premiere of Keeping Up With the Kardashians, which airs on Sunday, May 1, Kim is tired of the way her mom, Kris Jenner, coddles younger brother Rob — but the momager isn’t about to take the criticism sitting down.

“You should not be paying for your son, [who] is almost 30 years old, to buy a house,” the Selfish author, 35, tells Kris. Kylie, Khloé, Kourtney and Kris’ boyfriend, Corey Gamble, look on in silent agreement.

Khloé offers up her advice, making a scissors motion with her fingers.

“Drop him. Cut the cord,” she says with a stoic expression on her face.

Kris tries to keep her cool at first, but it’s clear that she’s frustrated by the way her girls are ganging up on her.

“You guys can judge me all day long, but we came here to have a nice dinner, so everybody just relax,” she says, looking around the table. “You all have to have somebody to blame and criticize instead of saying, ‘What’s the problem?’”

Kim interrupts her mom before she can finish.

“The problem is you!” Kim exclaims.

At that, Kris doesn’t hold back, throwing a particularly damning insult at Kim.

“All of you can f--k off and go think of something else to talk about,” the 60-year-old family matriarch says. “I’ve seen you guys through so much sh-t that you do that I have to f--king put up with. ‘I was married for 72 days.’ Really? Because that’s normal. … You guys can do anything you want, and it’s all OK and I’m supposed to accept it all. And I’m going to do the same thing for him, so stop judging me.”

Watch the fiery conversation in the clip above. The season 12 premiere of Keeping Up With the Kardashians will air on E! Sunday, May 1, at 9 p.m. ET.
