Kim Kardashian Gets Into Dirty Physical Fight With Her Sister Kourtney On KUWTK [Photos/Video]

Kim Kardashian West got into a dirty fistfight with her sister, Kourtney Kardashian, during the season 18 premiere of Keeping Up With the Kardashians (KUWTK) on Thursday.

The ongoing feud between the two sisters started when Kim and Khloé Kardashian wanted Kourtney to be fired from the show for showing up late and refusing to make the KUWTK a priority in her life.

While Kim had pointed out that the show is their job, Kourtney had chosen to focus on just being a mother to her children.

On Thursday, Kim first got into a little argument with Kendall Jenner, after Kim claimed that she and Khloé work the hardest in the family. That’s when Kourtney interrupted her saying, “You have this narrative in your mind,” before going off on Kim, who thought she was joking.

“I will literally f*** you up if you mention it again. Literally shut the f*** up and don’t laugh like that. You look like a freak,” Kourtney said, later adding, “But also, if I didn’t want to work my ass off and I wanted to be a stay-at-home mom, that’s f***ing ine.”

However, Kourtney was not joking and, to prove it, she chucked her coconutu water bottle at Kim before tackling her to the ground.

“What the f*** is wrong with you,” Kim asked while Khloé attempted to calm her sisters down.

“I swear to God, I’ll punch you in the face,” Kim told Kourtney, who responded, “So do it. Do it already.” And Kim did. She leaps up from her seat and punches Kourtney, while Khloe begs them to stop.

There’s some sort of karate kick moment, which Khloe tries to intervene on…

….And then more punching and slapping in a dark hallway. It sort of seems like the fight went on for a long time?

It’s not clear what exactly the two sisters were fighting about, or if they’re on better terms now — but the episode has got a lot of people talking.
