Ouch, Kylie Jenner!
In a new clip from this week's Keeping Up With the Kardashians, the 18-year-old reality star gets blunt when asked by sister Kim Kardashian if her and Kanye West could stay at her $2.7 million home while theirs is being renovated.
"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.
Despite their arguing, the Kardashians and Jenners are a tight-knit group, and in June, Kendall told ET that she feels so lucky to work with her sister.
