The upcoming season 15 of Keeping up with the Kardashians looks like the most explosive yet. Kourtney might not even finish as part of the family.

Turning Her Back On Family

A brand-new trailer has dropped online teasing Season 15 in all its glory, and to say it's dramatic would be a massive understatement.

First and foremost, the fieriest Kardashian, Kourtney, appears to be slinging accusations left and right, telling her famous sisters they're always giving her a hard time and that she's sick of it.

The short clip begins with the usual earnest intonation about family being important above all else. Then, a teary Kourtney tells Khloe, along with their other sister, Kim Kardashian West, that she's done with the two of them.

"I'm not gonna be around people that bring me down on a daily basis," she tells them angrily.

A previous clip for the new season also teased the blowup between the famous siblings, which saw the eldest Kardashian weeping as a result of 37-year-old Kim's words.

However, this latest teaser finds the KKW Beauty founder making the wildest proclamation yet.

"She doesn't want to be a Kardashian anymore," she says, to which, Khloe responds simply, "she can shove Kardashian up her f*****g vagina."

Kourtney's bad attitude is also alluded to by her ex and baby daddy Scott Disick, who is shown discussing how she keeps attacking him, seemingly for no reason.

So Many New Kardashians

Aside from the sisterly drama, another big topic on Season 15 will be Khloe's pregnancy and difficult relationship with partner Tristan Thompson. A source confirmed last month that their cheating scandal will be covered on the hit show.

"They always discuss real life things on the show. They've never ignored a topic. It will definitely be brought up, but ... Khloé is one of the executive producers and will have final say on what actually makes air," teased an insider.

This has been a particularly baby-heavy year for the extended Kardashian-Jenner clan in general, with Khloe giving birth in April to daughter True, Kim giving birth by surrogate to daughter Chicago in January, and the biggest shocker of all, 20-year-old Kylie Jenner giving birth to daughter Stormi in February.

Kourtney, meanwhile, who shares three young kids with Disick, has been focusing on her relationship with model and much younger beau Younes Bendjima. The two have been busy frolicking around Italy this summer, snapping romantic pictures at various tourist spots.

There was little context offered for her breakdown in this most recent teaser. However, it would have been filmed months ago, so everything is likely sorted out with Kourtney and her sisters by now.
