Kendall Jenner, usually the most cool, calm and collected of the Kardashian clan, proved she's not here for Caitlyn Jenner's tell-all in a rare display of frustration on "Keeping Up with the Kardashians."

In yet another sneak peek at Sunday's new episode, the model get fired up when speaking to mom Kris Jenner about some of the claims made in her dad's memoir.

"I spoke to Kim about dad's book and I heard about all the stuff she was saying in it and how a lot of it's really not true," Kendall says to her mother. "The weird part is, I don't think it's purposeful lying, I think she really just thinks that's what happened."

But Kris isn't having Kendall's semi-excuses for Cait, explaining in detail why she thinks some of the allegegations made in the book will have long-lasting, negative affects on the family.

"It could have been handled in the most amazing, loving way, talk about your journey and keep it to that. That I would have had great respect for," Kris says. "Don't talk about, in a real negative way, everything like I am such a bad person. There's lies that are printed in a book that lives there for the end of time. Your children are going to read this book about your grandparent and have a story that's fabricated, that's in print and is a fabrication."

Kendall then picks up what her mom is putting down and amps up some rage towards her dad.

"Yeah, you're right. And then she goes around dissing the Kardashians, but those are the kids you raised," Kendall says. "If you have a problem with them, you raised them! That makes no sense to me that she would go around bashing us for no reason. It's insane mom. That's insane!

Speaking with Andy Cohen back in April, Caitlyn said she and Kris haven't spoken since Kris called her up and "said she never wanted to talk to me again."

"I think her concerns with the book are legitimate. Her feelings are legitimate," she added. "I'm sorry she feels that way. I don't want her to alienate me from my children."

She also said she didn't give daughters Kendall or Kylie Jenner advance copies of the book until the day she left for her publicity tour.
