Just when you thought the Kardashians had run out of drama to bring to the small screen, season 18 kicks off. In the opening episode, Kim and Kourtney got into an *actual* physical fight, throwing punches, kicking and scratching.

Opening up about everything that went down, the KKW Beauty founder appeared on an episode of Jimmy Fallon’s The Tonight Show: Home Edition, where she revealed that cameras stopped rolling for an entire week after the pair’s fight.

“I don’t really ever resort to violence like that,” Kim said. “But she scratched me so hard, you couldn’t see, I had like – I was bleeding. And so you didn’t really get see that detail.”

“When I looked down at my arm and saw she had had really scratched me and I felt it all on my back, I just, you know, went over and slapped her back,” she said. “It’s not like my proudest moment but we were going through it.”

“We shut down production for a week after that,” she said before adding, “I think everyone was really shook for a minute and just was like, ‘this isn’t like our type of show.’ Like, what’s happening? We want everyone to be comfortable and safe.”
