The Kendall-Jenner clan is hardly one big, happy family, and Kendall is the latest member to enter the warring — she's calling out Caitlyn, her biological father, for being malicious.

In a preview of the next Keeping Up With The Kardashians episode, which you can catch exclusively at Us WeeklyKendall and mother Kris talk about Caitlyn's memoir, in which the former Olympian bashes her ex-wife and kids. And at first, Kendall approaches things diplomatically.

“I don’t think it’s purposeful lying. I think she really just thinks that’s what happened for some weird reason," Kendall says.

But after some thoughtful consideration, Kendall shifts her tone, and aggressively dismissed Caitlyn's motives.

“She goes around dissing the Kardashians, but it’s like, those are the children that you raised,” she says. “If you have a problem with them, you raised them. It makes no sense to me that she would go around bashing us for no reason. It’s insane, mom.”

Kris, herself, has been outspokenly against the book, and has insisted it's full of lies and fabrications.

“I read it and basically the only nice thing she had to say was that I was great socially at a party one time,” she's previously said on the show. “None of it makes sense. Everything she says is all made up. Why does everything have to be that Kris is such a bitch and an a–hole?”
