In E!’s Keeping Up With the Kardashians latest super-teaser, Jenner, 60, calls Kardashian West, 35, to share her extreme disapproval.
“Kim, you are a f–king traitor!” she said in the clip. “You’re not going to f–king play this game anymore!”
Earlier in the teaser, Khloé Kardashian provides context for her mom’s anger, as she explains the series of events to her best friend Malika Haqq.
“She’s so pissed that Kim was dressing Caitlyn Jenner for the ESPYs,” Kardashian, 32, explained in the video.
In July, Kardashian West talked about sort-of styling her former step-parent for the awards show.
“She wanted advice on what to wear,” Kardashian West previously told PEOPLE. “She gave me three days and said, ‘Can you get me something?’ I looked online. I shopped all over.”
And Jenner, 66, was more than grateful for Kardashian West’s help. She took to Instagram to share her appreciation, and captioned a photo with her, “caitlynjennerFeeling great, off to the#ESPYS 🙂 Thank you @michaelcostellofor the dress and @kimkardashian for your #styling help!!! // hair@courtneynansonhair / makeup@robscheppy / jewels @neillanejewelry.”

Kardashian West said the most difficult part of her styling gig was finding a dress that was long enough to accommodate for Jenner’s height, so she called up a friend for a bespoke look.
“I called Michael Costello. He was on Project Runway, so he has a studio in L.A. So he whipped up five things in two seconds,” she explained. “I sent her measurements. And she wore this white number … Really everything [looks good on her]. She’s super slim. She definitely likes to be age appropriate. But then she’ll like really short things. She seems to love clothes.”
