Kourtney Kardashian has been having an incredible time on holiday in Italy recently, as documented on her envy-inducing Instagram account.

Example A:

But behind-the-scenes there’s been some family drama going down, as revealed in a new trailer for the next season of Keeping Up With The Kardashians.

“I’m not gonna be around people that bring me down on a daily basis,” Kourtney says through tears in the season 15 (that’s right, 15 seasons) preview.

“She just fires missiles at me,” Scott Disick is heard saying over footage of he and Kourtney arguing.

“She doesn’t want to be a Kardashian anymore,” Kim Kardashian says as footage is shown of Kourtney walking out a door and slamming it closed behind her.

Kourtney is the eldest Kardashian sister, set to turn 40 next year. It’s entirely possible that approaching a new decade and having done 15 seasons of the show, the mother of three has had enough – especially since she’s in a new-ish relationship with Younes Bendjima. Could that be behind the tension?

We don’t have to wait long to find out – the new season premieres August 6.
