We all know that the Kardashian sisters are gearing up for the fifteenth season of their reality show 'Keeping up with the Kardashians.'

With the sisters—Kim Kardashian, Kylie Jenner, and Khloé Kardashian—welcoming their daughters, the drama revolving around babies is expected to be the key focus of the show.

While on the other side looking at the promos, fans are curious about Kourtney's altercation with the rest of her family. Kim had already revealed that her sister no longer wants to be a part of the Kardashian family.

Though fans are already aware of what's happening in the Kardashian family, Kourtney's anger comes as a surprise. It looks like the stress of filming her personal life for a reality show has taken a toll on her.

In the recent promo, it looks like the altercation between Kim and Kourtney is quite serious and this might continue for the entire season.

The feud began when Kim pitched the idea of a family Christmas photo shoot this year. A visibly excited Kim seems to be convincing every family member for the shoot as she is even organising the schedule to find a suitable time for the shutterbugs. However, Kourtney had other priorities that provoked Kim's temper.

"If I'm out by 4, that's all I need. If no one's going to be ready on time, and I'm like, lingering around... I'm leaving at 4 p.m. and I don't care what anyone says," Kourtney was seen screaming after Kim rearranged the schedule. The fight took an ugly turn when Kim hits back saying she is the "least exciting [sister] to look at." Interestingly, Kourtney is the only one among the sisters who do not have a brand attached to the Kardashians.

A teary-eyed Kourtney walks out of the house and in a phone conversation with Khloé, she makes it clear that she doesn't want to associate with people who mistreat her. She also added that her preference is her children and she is not looking for another job.

Things turned further dodgy when Kim, Kourtney and Khloé continued their frustration on Twitter.
