Khloe Kardashian was fuming after she found out her mother Kris Jenner told her a major lie about her ex-husband Lamar Odom.
WATCH: Khloe Kardashian discovers Kris Jenner LIED to her
In a teaser for an upcoming episode of Keeping Up With The Kardashians, Khloe's rollercoaster relationship with her ex is back up for discussion.
It seems that Khloe has finally read her ex-husband's autobiography, Darkness To Light, which was released earlier this year, and what she found in its pages sparked a huge fallout between her and her mum.
Khloe is clearly sensitive about the topic of her ex Lamar, who she met and married in 2009 following whirlwind relationship.
They hit the rocks in 2013, when Khloe served divorce papers on the two-time NBA champion, but she withdrew the documents after Lamar was found unconscious in a Nevada brothel so she could make medical decisions on his behalf.
They appeared to reconcile during his rehabilitation, however they eventually finalised the divorce in December 2016.
While the teaser doesn't say exactly what the lie is, it's clear it's something big and it leaves momager Kris doing "damage control".
In the clip shared on E! News, the Khloe tells her sister, Kylie Jenner, that she uncovered something very surprising in the book.
"In the book, I found out that mom's lying to me," Khloe said to Kylie, while looking visibly upset.
The Momager could then be heard saying, "I'm trying to do damage control," along with video of her scrolling through her phone.
The clip wraps up with Scott saying how worried he thinks Kris is after the revelation.
"She literally thinks you’re gonna, like, come for her," he told Khloe.
