Kourtney Kardashian and Kim Kardashian have oftentimes been seen fighting on “Keeping Up With The Kardashians.” Now a source claimed that the siblings’ fight has been so bad that they couldn’t stand each other both on and off camera.

A tabloid claimed that Kourtney and Kim have been fighting over the past couple of years. This is the reason why they can’t stand to be in the same room with each other.

“Kourtney has hated Kim for a couple of years now,” an unnamed source told the tabloid. “She thinks she’s vapid and mean, and Kourtney has much better things to do with her time than kiss up to Kim. Kim, meanwhile, thinks Kourt should kiss up to her given she would be a nobody without her,” the source added.

During a recent episode of “Keeping Up With The Kardashians,” the sisters opened up about their fight separately to their friends. The mom of three told one of her friends that Kim is going crazy. Kourtney, on the other hand, said that Kim sent her the meanest texts saying that she would die.

Kim also told her mom, Kris Jenner, that Kourtney accused her of having a lame lifestyle. Kourtney, meanwhile, called her younger sister a “fake humanitarian.”

And earlier this year, the sisters got into another major fight while planning their daughters’ birthday party. Even though they both agreed to host a candy-themed bash, Scott Disick’s ex-girlfriend wanted the snacks and treats for the kids to be healthy.

Kim couldn’t understand why Kourtney would want to serve such treats since it’s a children’s party, and candies are not supposed to be healthy. Following the incident, an insider said that the sisters’ relationship just got worse.

“Their egos have clashed big time and when the cameras aren’t on, they don’t speak,” the source said. “There are hints of their feud of course but the reality is they genuinely can’t stand each other,” the source added.

It’s important to note, however, that the claims of the unnamed sources have not been confirmed or denied by Kourtney and Kim. Though their onscreen feuds are real, it’s unclear if they’re really fighting off camera.
