Putting it all out in the open. Kris Jenner gives daughter Kim Kardashian a piece of her mind in Keeping Up With the Kardashians' season 12 premiere on Sunday, October 23, as seen in a sneak peek.

The E! unscripted series' preview clip shows Khloé Kardashian mentioning that Kris isn't pleased about Kim helping Caitlyn Jenner plan her wardrobe for the 2016 ESPY Awards. The sisters, who discuss the situation with pal Jonathan Cheban, then decide to give Kris a call to clear the air.

"Kim, you are a f--king traitor, that you would have the nerve to help Caitlyn to pick a gown," Kris says. "Like, what is going on?"

Kim, 35, explains that she thought her mom, 60, and the former Olympic hero, 66, were currently on good terms: "I'm just trying to stay neutral and not get involved." Apparently, this was the wrong choice of words.

Kris replies, "I don't want you to be neutral — from my children that I gave birth to. I want loyalty. I don't want f--king neutral."

"Neutral isn't what I signed up for," she continues. "That was what you don't get. I'm trying to be as gracious as I can. I'm trying to be as understanding as I can. I'm betrayed. I've been f--ked over on so many levels that your head would spin."

In July, Kim helped Caitlyn select a lovely Michael Costello dress to wear for the sports awards ceremony.

Watch the tense clip above. Keeping Up With the Kardashians airs on E! Sundays at 9 p.m. ET.
