Here's What Caused Kim & Kourtney Kardashian's Physical Fight On 'KUWTK'

Kim and Kourtney Kardashian came to literal blows on the latest episode of Keeping Up With the Kardashians.

The sisters' longtime feud turned physical after a conversation about their differing work ethics where Kim noted that she and Khloe are the hardest working sisters.

"The problem is if I were on my deathbed, I would still show up," Kim told sister Kendall Jenner before turning her attention to Kourt. "And mom is so used to me, Kourtney — and Khloé going on our death beds... you don't care about stuff..."

"You act like I don't do sh*t! You have this narrative in your mind, Kourtney interjected before standing up to approach Kim. "I will literally f**k you up if you mention it again... But, honestly, change the narrative in your mind. I work my f**king ass off."

Kourtney then proceeded to push Kim on the floor. "I will literally f**k you up," she said as Kim kicked her in retaliation.

"What the f**k is wrong with you?" a shocked Kim asked. "Don't ever come at me like that. I swear to God, I'll punch you in your face."

Kim went on to punch Kourtney in the arm and the situation escalated from there with the two kicking one another and Kourtney "digging her nails" into Kim's arm. While Khloe tried to step in to calm the situation down, the sisters continued to go at it with Kim ultimately slapping Kourtney across the face.
