And tension between the two siblings had been brewing for quite some time. As Kourtney revealed on The Kardashians’ Oct. 29 episode, she dipped out of family group chat because she was “exhausted” by Khloe “talking s–t.”

“Khloe is just talking negatively about somebody who posted something,” Kourtney explained at the time. “And I’m like, ‘Really?’ This is not what we have time for, and I just said, ‘Let them live their lives, you know?’”

As for Khloe, she took issue that Kourtney did not side with her during the family discussion.

“I was talking to Kylie [Jenner] and Kris [Jenner], who chimed in. And Kourtney was like, ‘Can’t you just let people be who they are?’” the Good America founder recounted. “You’re defending someone—and I said, ‘Can’t you give me the same energy,’ basically.’”
