We think it's safe to say the whole family hates her!

Kim Kardashian trashes Caitlyn Jenner in a newly released sneak peek of Sunday’s season 14 KUWTK premiere, and it's all over claims the Olympian made about Kim's dad Robert Kardashian Sr. in her memoir Secrets of my Life.

Kanye's wifey and Kourtney go to Cleveland to visit Khloe, and get a news alert about the I Am Cait star's comments.

"It says in Caitlyn’s book Robert Kardashian knew O.J. Simpson was guilty, but joined the defense team to get back at his re-married ex. Robert told Caitlyn in secret after the O.J. murder trial that he believed his friend was guilty," Kim says as she reads the report.

"Dad so believed in him. It is so shady that Caitlyn came over and gave me the book, and then on the phone she said, ‘Well, the final version has a few more things in it, but don’t worry, it’s nothing about you.’ So she lied to me, because that is about me, if it’s about our dad. I have always had Caitlyn’s back. But she is a liar. She is not a good person," she fumed.

The transgender star really knows how to piss people off! It's almost her biggest talent!
