AceShowbiz - The Kardashians sisters fight over almost everything, and this time around it's all stemmed from their different opinion on their kids' birthday party. In the Sunday, November 17 episode of "Keeping Up with the Kardashians", Kourtney and Kim Kardashian went at it as the former refused to have a Candyland-themed birthday party.

As for the reason, it was because Kourtney Kardashian wanted North and Penelope's joint bash to be filled with healthy food, and candies were in no way healthy. Thus, she offered options that didn't include "nasty stuff with food coloring and gross s**t." Kim obviously was not having any of it, leading the sisters to fight.

"She is insane. She is actually insane. She wants to have a Candyland themed party but can't have any candy. She is just not my vibe," Kim said, before her older sister ranted back, "Kim and I have been fighting again today about the kids' birthday party and how we don't have to do a candy-party full of junk."

Things got worse after that, with the Skims founder calling Kourt "a buzzkill" and even planning to throw separate birthday parties on the same day. Seeing this, Khloe Kardashian felt the need to mediate and help resolve their issues. She set up a face-to-face peace-making conversation between her sisters later on, allowing Kim to say, "I feel like you very often times think that you are right no matter what." Kourtney answered back, "Because I usually am," before getting coaxed by Khloe.

"I think, in this family, if we're not the same, we're not supporting our differences. We're really criticizing and judging our differences. But can't you support our high fructose corn syrup differences too?" Khloe told Kourt, making her soften her attitude.

In the end, Kourt managed to come around and apologized to Kim. "I'm sorry if you think that I just want it my way. This is really about the kids, so I'm OK with come candy and having sugar. You only live once," she said.
