Keeping Up with the Kardashians is coming back into our lives on Sunday, and the premiere episode will focus on the strained relationship between Caitlyn Jenner and her family.

In a clip from the season premiere, Kim reads a section of Caitlyn's memoir out to Khloé, saying, "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...Robert told Caitlyn in secret after the O.J. murder trial that he believed his friend was guilty."

Khloé's shocked response? "That's not true....Like, what?"

Kim added that, "Dad so believed in him," at which point Kourtney accused Caitlyn of lying: "Like to sell a book, you're gonna make something up?"

Kim seemed to agree, saying, "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 explained how hurt she was by Caitlyn's actions, saying, "I have always had Caitlyn's back. She is a liar. She is not a good person."

Dang, looks like this season of KUWTK is going to have even more drama and tension than usual...
