Kris Jenner Calls Kim Kardashian a 'F--king Traitor' for Helping Caitlyn: Find Out Why

Kim Kardashian is feeling the wrath of Kris Jenner. In a new superteaser for the return of season 12 of Keeping Up With the Kardashians, the momager calls her daughter out for styling Caitlyn Jenner before the 2016 ESPY Awards.

"Look what my mom sent me," Khloé Kardashian tells her best friend Malika Haqq as she hands over her cellphone. "She's so pissed that Kim was dressing Caitlyn for the ESPYS."

Moments later, Kris, 60, angrily calls Kim, 35, on the phone, saying, "Kim, you are a f--king traitor! You're not going to f--king play this game anymore!"

The Selfish author appears to be stunned by her mom's reaction, sitting in complete silence as Khloé, 32, and close pal Jonathan Cheban look equally horrified while listening to the speakerphone conversation.

In July, Kim helped Caitlyn (who finalized her divorce from Kris in December 2014) get ready for the prestigious sports awards ceremony, helping her select a stunning white Michael Costella dress. A year earlier, the former Olympic athlete, 66, received the Arthur Ashe Courage Award at the ESPYS following her gender transition.

Kim and Kris' phone call isn't the only drama teased in the new KUWTK promo. The two-minute clip also gives fans a glimpse of Kourtney Kardashian's ex Scott Disick helping Rob Kardashian prepare for the birth of his first child with fiancée Blac Chyna.

Meanwhile, Khloé considers getting a boob job, telling the camera, "We're in L.A. People get their boobs done like they fill up a car with gas."
