On the upcoming episode of E!'s hit reality TV series "Keeping Up With the Kardashians," Kris Jenner and Kim Kardashian West argue over rare slabs of marble that Kardashian-West need to finish decorating the bathroom for her husband, Kanye West, in their new home. In a new sneak peek obtained by People, what starts out as a mother-daughter spat turns into a casual $1 million wager.

"When we moved in with my mom the first time, we bought a whole ton of marble - all these slabs from out of the country. She took my marble, has never mentioned it, has never paid for it, and now I have to figure out a new plan," Kardashian West, 35, explains in her on-camera interview.

"Kim, let very kindly -" the 60-year-old momager says in the clip as she approaches her pregnant daughter and Kardashian West tries to cut her off.

"I had to change Kanye's whole bathroom," Kardashian West says.

"Really? Really?!" Jenner asks incredulously. "Because you didn't have one slab of marble?"

They bicker back and forth about how many slabs of marble were taken. Jenner says that she only took six, but Kardashian-West says that she knows her mom took 10 because of an invoice.

"You're charging me for the marble?" Jenner asks.

"Absolutely," Kardashian West responds.

Kardashian West explains to her mom that the "Calcutta gold" marble she purchased was from Italy and is out of stock, which is why she's so upset that Jenner took it in the first place.

"How much would you give me if I find you 10 slabs of Calcutta gold?" Jenner asks.

The women bet $1 million that Jenner can somehow find her daughter the specific color of marble she needs to finish her husband's bathroom.

"If I have to rip it out of that bathroom, I will find you 10 slabs," Jenner says.
