Kris Jenner felt "abandoned" by Kim Kardashian West when she styled Caitlyn Jenner for the ESPYs.
A teaser trailer for the upcoming midseason premiere of 'Keeping Up With the Kardashians' showed the 60-year-old matriarch branding her daughter a "traitor" for agreeing to help her stepparent - who was known as Bruce while married to Kris before undergoing a gender transition - and now a full promo clip saw the 35-year-old beauty labelled "disloyal" by her mother.
In the footage, Khloé Kardashian told Kim: "Mom is like, fuming with you. She was texting me with hashtags -- she goes, '#Disloyal.' ... She thinks you're a traitor and she thinks that you went against the family with Caitlyn. She's p***ed."
While Kim rolled her eyes at the news, they decided to call Kris to work things out.
However, Kris ranted: "Kim, you are a f***ing traitor. That you would have the nerve to go to help Caitlyn to pick a gown -- like, what is going on?"
While her daughter tried to defend herself, explaining Caitlyn had had a "fashion emergency" and that as far as she knew, things were "all good" between the former couple.
Kris replied: "That's what you don't get! I don't say anything to you until I feel abandoned. And right now, I'm feeling abandoned."
But the brunette beauty insisted: "Mom, I would never abandon you. If I even knew that you really thought..."
She was cut off by her mother, who said: "But you abandoned me! You've taken somebody else and said, 'OK her feelings don't matter.' "
Kim insisted she didn't think her mother "would care" and, in a bid to calm the situation, promised that in future she would "try to stay neutral and not get involved."
However, her words didn't go down well and Kris burst into tears, insisting she needed Kim's "loyalty".
She said through her tears: "I don't want you to be neutral. From my children I gave birth to, I want loyalty.
"I don't want f***ing neutral. Neutral isn't what I signed up for. That's what you don't get.
"I'm trying to be as understanding as I can. I'm betrayed. I've been f***ed over on so many levels that your head would spin."
As Kim - who has children North, three, and Saint, 10 months, with husband Kanye West - and Khloé exchanged shock glances, Kris insisted she wouldn't back down.
She told them over the phone: "I'm not going to play this f***ing game anymore. OK?!"
