All of the drama brewing on Keeping Up With The Kardashians came to a head in last week's episode, with the tension between Kim and Kourtney devolving into a fist fight that left Kim with bloody scratches on her arms and back.
When she was recounting the story to Jimmy Fallon, Kim explained that they were both pretty embarrassed by their behavior.
"It’s not, like, my proudest moment, but we were going through it. When my mom saw that, a clip of that, she cried. She was like, 'Who are you guys? What is going on?'"
