VIDEO : Tempers Flare On Keeping Up With The Kardashian's Premier

"Keeping Up With the Kardashians" returned this week with a blowout fight between Kim and Kourtney.

Business Insider Reports the drama began with Sunday's season 15 premiere episode. In it, Kim is trying to organize the family's annual holiday photo shoot. The sisters' schedules conflict, but Kim feels Kourtney should be the one to yield because she doesn't work as much.

The argument culminated in Kourtney calling her sister "a very distraught, evil human being." The sisters continued to duke it out on Twitter after the episode aired.

Based on one of Khloe's tweets, it seems things are going to get worse on this new season before they get better.
