Kim Kardashian West wasn’t lying when she said her relationship with Kourtney “gets worse before it gets better”.
WATCH: Kim punches Kourtney in an explosive argument
In the latest trailer for the upcoming season of Keeping Up With The Kardashians, the gloves come off as the once-close sisters square up for a fight that eventually resulted in the KKW Beauty founder throwing the first punch.
The sneak peek begins with Khloe Kardashian telling the mum-of-three that she can’t stand her “bad attitude”, before Kourt pipes up and screams, “don’t involve yourself in business that is not yours.”
“Then don’t talk about it in front of me,” she fires back.

The clip then cuts to another scene showing Kim and Kourtney fighting again, with the Poosh founder quickly getting out of her chair to throw a water bottle at her younger sister.
“You’ve got nothing to say?” she yells, angrily pointing her finger in Kim’s face before pushing her to the ground.
“Don’t ever come at me like that,” Kim warned before launching at Kourtney and hitting her face.

It’s no secret Kourtney and Kim have been at each other’s throats for years, with Kim revealing in December that despite the fact they’re now working on repairing their fractured bond, we will see their relationship deteriorate even further on season 18.
“What sucks is that season 18 will come out soon and it gets worse before it gets better,” Kim said while appearing on Ellen DeGeneres’ talk show. “But her and I have healed and have talked about everything and really come to an understanding.”
Tension reached an all-time high during the season finale of KUWTK when Kourtney admitted she was at breaking point and, as a result, had no choice but to quit the series. While Kourtney said no longer taking part in the series was the best decision for her, Kim told Ellen she’s still furious she’s been forced to pick up her slack.
“If one family member goes on vacation a lot or takes time off a lot, the other family members have to step in and take over those hours,” she continued. “So for the past year, Khloé and I have been taking over her hours, working, because we need content to make the show.'”
“It’s been exhausting for us when she hasn’t taken that into consideration without making a decision of what she wants to do,’ she said. ‘Stay on the show, not, but to be in this limbo and have us do this for so long is frustrating.”

Nevertheless, Kim said she’s focusing on getting their relationship back on track, urging her sister to put the past behind her and focus on moving forward.
“We’ve come to the conclusion that [Kourtney will] film a little bit,” she hesitated to say. “I don’t even know if we have a conclusion, actually. It’s always up in the air. But we’re in a good place about respecting each other’s space. And if someone doesn’t want to be on the show, we obviously want them to have that mental break and live their life exactly the way that they want.”
