Kourtney Kardashian is sent "over the edge" on this Sunday's Keeping Up With the Kardashians after seeing a Chymoji of Blac Chyna slapping a Kylie Jenner look-alike. After seeing the Chymoji, Kourtney decided to call Rob Kardashian to give him a piece of her mind.
"Everything with Rob, I always try to be super calm but I was just like in a mood," Kourtney tells her makeup artist Mario in the clip above. "So I was gonna call Chyna and then Kylie was like, 'No just call Rob, it's too crazy to call Chyna.' And I'm like I don't want to yell at a pregnant person."
"So wait what did you say to Rob?" Mario asks.
"I yelled at him," Kourtney admits.
Kourtney then explains that this is the first time that she's had to "question Chyna's intentions" and this just set her off.
When Kourtney called Rob he denied that it was Kylie in the Chymoji and Kourtney says it "really upset him."
Kourtney then tells Khloe Kardashian that Rob told her, "I'm gonna go on the red carpet tonight and I'm gonna tell everybody how I have the worst, most unsupportive, disgusting family."
Check out the clip above to see what else Kourtney and Khloe said about Rob, Blac Chyna and Kylie!
