Kim Kardashian is not happy with Caitlyn Jenner. The “Keeping Up With The Kardashians star has slammed Caitlyn, formerly known as Bruce, for spilling stories about her mom, Kris Jenner, in her new memoir, “The Secrets of My Life.” Yahoo TV posted a clip from the most recent episode of the Kardashian clan’s E! reality show, in which Kim gives her former stepdad a serious warning: “I’ll let you know if I’ll still be speaking to you after I read this book. Talk bad about my mom, I come for you.”

Turns out, Kim and Caitlyn probably aren’t on speaking terms anymore. Kris and Caitlyn sure aren’t.

Kim fires back at Caitlyn's book secrets

In the episode, Kim Kardashian credits her family for giving Jenner “more life” after she faded from the spotlight three decades after Bruce’s Olympics fame.

Kim made fun of Caitlyn, saying no one even knew who she was “for the last few decades” until the Kardashians landed the E! reality show and she was back on TV.

Kim also slammed Caitlyn for starting three families—with wives Chrystie Crownover, Linda Thompson, and Kris Jenner—and then leaving them all high and dry while she figured out her gender dysphoria issues. Jenner’s daughter, Kendall, admitted that Caitlyn is pushing the family “further and further away from all of us.”

Caitlyn Jenner dished several Kardashian secrets in her book, even accusing her ex-wife Kris of hoarding the couple's money during their 23 years together. Caitlyn also alleged that Kris knew all about her desire to transition to a woman well before they had two children together. Kris has denied Caitlyn’s recollections of their relationship, and Kim Kardashian recently told Bravo host Andy Cohen that she doubts the two women will ever speak again.

Jenner expected a negative reaction

While Kim Kardashian is defending her mom, the Kardashian clan’s outrage [VIDEO] comes as no surprise to Caitlyn, Jenner previously told “Good Morning America” she knew the supersized clan would react strongly to her book. But the former Olympian also added that she thinks some of the drama is exaggerated because the family is on a reality show. Jenner told “GMA” she’s sorry that Kris “went down that road,”

Jenner then went on to insinuate that Kris and the rest of the Kardashian clan are ramping up the drama for their reality show. Caitlyn acknowledged that her ex is “a good person, and we’ve had 23 great years together and raised wonderful, phenomenal kids.”
