Kris Jenner Says She's 'Done' With Caitlyn After Reading Her Memoir: 'Everything She Says Is All Made Up'

Don't mess with Kris Jenner.

The gloves are off.

In a new clip from Sunday's Keeping Up With the Kardashians, Kris Jenner doesn't hold back when it comes to her thoughts on her ex Caitlyn Jenner's upcoming memoir, The Secrets of My Life. Kris says she's portrayed as a "b**ch and an a**hole" in the book, and definitely isn't having it.

"I read it and basically the only nice thing she had to say was that I was great socially at a party one time," Kris tells her daughters Kim and Khloe Kardashian in disbelief. "None of it makes sense. Everything she says is all made up. Why does everything have to be that Kris is such a b**ch and an a**hole?"

Kris also refutes Caitlyn's claim that the 61-year-old momager knew she was transgender very early on in the relationship.

"I was curious and said, 'What the hell is going on?' She said, 'You just would never understand,'" Kris claims about their previous conversation. "And then, all through the book, 'Kris knew. Kris knew before I even made love to her.' I'm like, 'What?'"

The mother of six is clearly through salvaging their relationship.

"I really tried hard to improve the relationship and spend a little bit of time, thinking maybe there's something here that I'm not seeing," Kris says. "I've done nothing but open up my home, and my heart, to a person who doesn't give a s**t. So, I'm done."

"I've never been so angry and disappointed in somebody in my whole life," she adds.

Later, Kris tells the cameras that she's ready to stand up for herself.

"I'm not gonna be used as a person who benefits someone else's life just to make them look better," she says. "I just can't sit back and be an enabler anymore."

Caitlyn's relationship with both Kris and 32-year-old Khloe has been rocky since her decision to come out as transgender. Earlier this month on KUWTK, Khloe and Caitlyn put their tension out into the open when they sat down to talk about why they've lost touch over the past year.

"Day after day, month after month, nobody calls, nobody checks in," Caitlyn told Khloe. "Just, 'Hey, how are you doing?' I haven't gotten that phone call from anybody. You can't help but sit there and think, 'OK, is it because I transitioned? They don't like me anymore?' I want to know what I did wrong, what I didn't do wrong, what I did right, and move forward."
