Khlo Kardashian , livid after her ex-husband Lamar Odom s memoir revealed that her mother, Kris Jenner , had lied to her, said she was going to come for the KarJenner matriarch.

On Monday, a clip from the upcoming Sunday episode of Keeping Up With The Kardashians showed Kardashian telling her younger sister Kylie Jenner that Odom was writing a book.

In the book, I found out that moms lying to me, she says.

The memoir, Darkness to Light, came out in May and did include some juicy details about what potentially helped end Odoms seven-year marriage to Kardashian. The clip doesnt note exactly what it is that Kardashian learned, but based on coverage of the memoir when it was released, its likely that the event in question was this dramatic run-in outside a SoulCycle studio in August 2015. Odom alleged in the memoir that Kris Jenner orchestrated the entire event.

Odom wrote in the memoir that Jenner called that August to tell him that her daughter wanted to speak to me in person the next day in LA.

While on a drug binge, Odom went to Los Angeles to see his then-wife.

Kris said Khloe would be at SoulCycle in Beverly Hills at 6 AM, and she was right on time, wrote the basketball star.

Kardashian was stunned at his presence as the unhappy duos reunion was inundated by paparazzi.

It had to be Kris. She must have called the paparazzi and arranged for them to be there, knowing Khlo would be caught off guard and react accordingly. Now heres the kicker and this will show you how devious Kris Jenner is Khlo had no idea I was going to be there. She was frightened and jittery. From the outset it looked like I was ambushing her while she walked to her workout. We were on bad terms and she didnt want me there. It all began to make sense, Odom wrote .

The cameras caught the entire encounter on tape, he recalled. There had been a sliver of hope for us to reconcile. I wanted to get back together. Kris knew this was my last chance, but she didnt want a drug addict in the family. It wasnt good for business. Any chance I had left with Khlo exploded on the spot.

Given that this revelation is pretty explosive and hella shady on Jenners part it wouldnt be surprising if its what set Kardashian off.

In another part of the clip for next weeks episode, Scott Disick is heard telling Kardashian about her mum: She literally thinks youre gonna, like, come for her. Without missing a beat, the Good American founder says, Guess what? I am.

Yikes. Youd think after all these years wed be better at keeping up with these wild Kardashians and yet ... well still be tuning in on Sunday to see for sure what sparked the drama this time.
