It seems like the feud between Kim Kardashian and Caitlyn Jenner is not going away anytime soon. In the Sunday episode of "Keeping Up with the Kardashians," Kim confronted Jenner regarding the content of her new memoir, and warned her about saying bad things about Kim's mom, Kris Jenner.

Caitlyn Jenner, formerly known as Bruce Jenner and Kris Jenner's ex-husband, recently made waves by publishing a memoir called "The Secrets of My Life." In it, Caitlyn recalled highlights of her life, up to the point of her becoming Caitlyn. Of course, mentioning Kris Jenner in the book could not be avoided.

The book was one of the focal points of Sunday's "Keeping Up with the Kardashians" episode.

Kris Jenner asks for Kim Kardashian's help with 'The Secrets of My Life'

In a report by People TV Watch, it was said that there was one scene where Kris Jenner asked Kim to "help her out" by reading Caitlyn's memoir. This is because she thought she was overreacting to some of the content in the book and she thought that she needed impartial eyes.

Even though Kim did not want to get caught in the middle of whatever the former couple's problems are, she still agreed. Caitlyn Jenner did come over so that she and Kim could talk about the book. As they did, Kim was so up front about her feelings about the book, and she did not hold back in terms of what she wanted to say.

Kim Kardashian threatens Caitlyn Jenner

"I’m going to read it and tell you honestly. Talk bad about my mom, I come for you," the 36-year-old Kardashian said. She did start by saying that Caitlyn's feelings are her feelings, but added that her mom Kris feels a certain way about Caitlyn, too, and "she has the right to be upset."

Caitlyn responded by saying that the book is "her story." She said that there are certain things that everyone has to deal with in life, and people always find ways to deal with said things.

This is her way of dealing with her issues.

Kim did read "The Secrets of My Life" cover-to-cover, and it seems her threat will be put to the test. In the same article from People, it was reported that Kim "was not happy" with the way her mother was portrayed in the memoir. Apparently, Caitlyn wrote that she felt like a "punching bag" throughout her relationship with Kris.

Also, Caitlyn claimed that the 61-year-old mother was hoarding money.

At the time of this writing, there have been no reports of Kim Kardashian following up on her threats; however, it is clear that both she and her mother were infuriated by the book's content.

"I do feel like there’s a way to tell your side of the story without being so negative," Kim said.
