"I would seriously stab myself," Kylie says when Kim brings up the idea. "No one is staying at my house."
"I don't know why they are being so rude and dramatic," says Kim, when her mom Kris doesn't want to take the couple in. "They should want to cater to a pregnant woman."
This is not the first altercation Kylie has found herself in during the show's 11th season. On the season premiere, Kendall Jenner called her younger sister "the biggest f**cking b*tch I've ever met" after the reality star refused to let her borrow some clothes from her closet.
"It's really awesome," she admitted. "Not everyone can say they work with their family every single day."
Keeping Up With the Kardashians airs Sunday at 9 p.m. on E!
