Caitlyn Jenner has landed herself in hot water once again.
In this preview from Sunday's premiere of Keeping Up With the Kardashians, Kim Kardashian finds out some controversial things Cait has included in her memoir.
"It says in Caitlyn's book Robert Kardashian knew O.J. Simpson was guilty but joined the defense team to get back at his remarried ex," Kim reads aloud to her sisters. "Robert told Caitlyn in secret after the O.J. murder trial that he believed his friend was guilty."
"That's not true. Like, what?" Khloe Kardashian says.
"Dad so believed in him," Kim adds.
"Like to sell a book, you're gonna make something up?" Kourtney Kardashian reacts.
"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," Kim says, later adding, "If you talk about my dad I will cut you."
"I have always had Caitlyn's back," a saddened Kim says. "She is a liar. She is not a good person."
