'Keeping Up With The Kardashians' Kris Jenner, Bruce Jenner Divorce Drama: 'KUWTK' Star Is A "Controlling Monster" According To Mother-In-Law!

Keeping up with the Kardashians star Kris Jenner is trying to keep civil in the middle of her divorce with ex Bruce Jenner, but that is going to be hard to do now that the Olympic gold medalist's mother has spoken out bashing Kim Kardashian's mama.

In an exclusive interview with the MailOnline, Esther Jenner had no problem talking about her disdain for Kris. When asked if the E! star was a "controlling monster," she said, "That's accurate. I don't know why she is. I don't think she treated anybody very well. She could insult you with a big smile on her face. What do you do with a person like that? You're going to avoid them if possible. She was backstabbing as far as my grandchildren were concerned, and that is something I can't stand."

Esther goes on to talk about how great her son is doing now that he is divorcing that "controlling monster."

"He is ecstatically happy right now," she exclaimed. "When I talk to him, I can hear it in his voice... Since he has got his freedom he has his own checkbook and doesn't have to ask Kris for money which he's had to do, he couldn't even buy one of his little helicopters without asking her for money."

The reality star's mother hates her daughter-in-law so much she doesn't even want her to keep Jenner as her last name!

The 88-year-old's disdain doesn't stop at Kris. Apparently, she doesn't like Kim or Kourtney either.

"Oh my God, the ways the girls display themselves ...  and it's all surgical work they've had done, what are they trying to prove?" she said, according to PageSix. "Kris hasn't brought them up with any morals, you know, go out and go sleep with anybody... that sort of thing, you wouldn't tell your own children to do that.

"When Bruce and Kris got married I think Kourtney was maybe a freshman, Kim was probably junior high, Khloe was quite a bit younger and had the best personality, the other two weren't even interested in having a conversation with me, they were in a world of their own," she continued in the Daily Mail interview.

What do you think of Bruce's mother's tell-all? Is she too bitter?
