Kris Jenner thinks her daughters need help.
In a new preview clip from this Sunday's Keeping Up With the Kardashians, the family matriarch plans to set up a meeting with a professional to talk to Kim and Khloe Kardashian about how much time they spend on their cellular devices.
"You're never not on your phones," Kris says, explaining that she's contacted one of Kourtney's friends from college who specializes in communication. Unfortunately, Kim and Khloe are less than enthused.
"That's the dumbest thing I've ever heard in my life," contends Kim.
Khloe adds: "I'm always the one who tells you, 'Put your phone down, we're at dinner.'"
Meanwhile, technology isn't the only thing creating a bit of friction for the family.
In another clip, Kris and Kim are literally stuck between a rock and a hard place over missing slabs of marble.
"When we moved in with my mom, the first time, we bought a whole ton of marble," says Kim. "She took my marble. Has never mentioned it, has never paid for it."
Kris argues that she only took six slabs of the marble, but Kim contests that not only did her mom take 10, but now Kim wants payment for the marble she took.
"They don't have that same marble," she says. "I have Calacatta gold. It's only from Italy."
"How much will you give me if I find you 10 slabs of Calacatta gold?" Kris asks.
"One million dollars," says Kim.
