We've all gotten in fights with our siblings on a reality TV show. Okay, we haven't, and that's a good thing. When you get a fight with someone, you try to say the most hurtful thing, to win the war of words. Then, once you cool off, you regret it and apologize. If that outburst was caught on camera, you'd probably feel ashamed.

Thankfully, the Kardashians have no shame! Their reality show is about start its 15th season - yes, 15th - and shows no signs of stopping. Forget the feud between The Hound and The Mountain on Game of Thrones, because the feud between Kim Kardashian and Kourtney Kardashian is much more intense.

In a clip released yesterday, Kim and Kourtney get into an explosive argument. Kim's trying to coordinate a Christmas card photoshoot, which is difficult, since everyone in the family has a different schedule. Kourtney says she has to leave at 4pm on the proposed day, which throws a wrench into the plan. Kim accuses Kourtney of being "difficult," to which Kourtney responds, "get the f*** out of here!"

Then the real fireworks came. Boiling with rage, Kim shouts, "Maybe if you had a f***ing business that you were passionate about then you would know what it takes to run a f***ing business, but you don't, so don't even act like you know what I'm talking about!"

As Kourtney storms out of the room, Kim drops the most savage diss: "I need Kourtney to not be so f***ing annoying with a stick up her ass like she f***ng runs this sh*t, because she doesn’t. She’s the least exciting to look at, so she can be out." Ouch.

Today E! released a new clip from Keeping Up With The Kardashians, and the drama continues. Following the fight with Kim, Kourtney calls Khloé. The socialite is in tears, claiming her sisters don't share her "values."(Thankfully, Kourtney's off screen in this scene, because she's the least exciting to look at.)

"I'm not here to f*cking be mistreated by my f*cking bitch family. Kim saying that I'm the least interesting to look at…who even speaks like that? ... I choose to be a mother to my three kids. I'm not here looking for another job. I already work enough, more than I would like to."

After hearing Kourtney pour her heart out over the phone, Kim realized she was wrong, and apologized for her petty insults. Just kidding! She slammed Kourtney again. "You do whatever the f*ck you want to do and you don't do shit," said Kim. "So be accommodating to the people that actually do shit."

Because nobody works harder than Kim Kardashian - have you ever tried uploading naked photos on Instagram to sell perfume? Anyway, this time, Kourtney comes back with the most savage diss: She tells Kim, "You're a very distraught, evil human being. I don't agree with who you are as a human being." Ohhhhh! Wherever Kourtney's calling from, I hope she dropped a mic after that line.

The new season of Keeping Up With The Kardashians premieres this Sunday. Hopefully it ends with Kim and Kourtney working out their issues in a no holds barred steel cage match.
