Bruce Jenner's mom says Kris Jenner is a controlling monster in an exclusive no-holds-barred interview with the Daily Mail Tuesday.

The 88-year-old also said she isn't in favor of Bruce's rumored womanly transformation although he has been happier since the divorce.

"I have to be truthful. One thing I'm not, I'm not a phony, and I get in a lot of trouble sometimes for saying it like it is," Bruce's mom said to the Daily Mail while sitting in her Idaho home.

She referred to Kris being a controlling monster, "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," the former Olympian's mother said.

"She's domineering - it's do it her way, or there's no way. I had very little to do with Kris. I stayed away from her as much as I could," Esther said.

Bruce's mom explained how happy he is without Kris. "He is ecstatically happy right now," she said.

"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," she shared.

She said when she heard of the news of the divorce she said, "Hallelujah."

Esther also wants the momager to drop the Jenner name because she's not fit to carry their family name.

Bruce's mom said the hatred towards her son's ex-wife of 23 years started in 1991 because Kris never cooked while Kendall and Kylie Jenner were growing up and she always left Bruce to take care of them.
