Kim Kardashian is going through a pretty rough patch with Caitlyn Jenner at the moment, and it doesn't look like things are going to ease up anytime soon.
In a sneak peek from the upcoming season 14 premiere of Keeping Up With the Kardashians, Kim is alerted about news that Caitlyn has tried to throw her father, Robert Kardashian, under the bus about the O.J. Simpson trial.
"It says in Caitlyn's book, 'Robert Kardashian knew O.J. Simpson was guilty, but joined the defence team to get back at his re-married ex,'" Kim reads from her phone to her sisters, as People reports.
"Robert told Caitlyn in secret after the O.J. murder that he believed his friend was guilty."
All sisters were pretty angry after hearing the news.
"That's not true! Like, what?" Khloe yells, before Kourtney adds. "Like to sell a book, you're gonna make something up?"
Apparently, this segment wasn't in the version of the book that the sisters were given before its release.
"Dad so believed in him," Kim continues. "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.
"She is a liar. She is not a good person," Kim concludes.
Later in a confessional, Kim talks about her changed relationship with Caitlyn.
"My relationship with Caitlyn was strained. I was just trying to be respectful. But if you talk about my dad, I will cut you."
