Kourtney Kardashian and Khloe Kardashian have got into a heated row in a sneak peek of Sunday's season premiere of Keeping Up With The Kardashians.
In a newly released clip, Khloe and sister Kim sit anxiously waiting for Kourtney to turn up to a meeting, and the tensions are already high.
Khloe tells Kim, 'I don’t understand [her] f***ing attitude.'
Kim then claims she’s 'so afraid' of Kourtney.
Kourtney then arrives, and she immediately begins typing on her phone, ignoring the conversation.
Meanwhile, Kim is discussing the baby shower she threw for herself ahead of daughter Chicago's arrival.
'I really wasn’t going to plan a baby shower, but I think it’s important for North so she starts feeling that it’s coming,' she explains.
Khloe offers to help and turns to Kourtney, who quickly changes the subject.
She asks Khloe, 'Who let you choose black covers for your furniture?'
'Disgusting,' she says. 'Usually people get a colour that’s like, neutral to your floor. Who chooses black?'
Khloe quickly replied, 'That’s nice, Kourtney. Thanks for coming over, thanks for being so lovely.
'When I come into your house, I’ll make sure to say just a critical comment.'
The two sisters begin arguing back and forth and Khloe eventually snaps.
'What is up your a**?' she demands.
'Seriously, what the f**k is wrong with you? Why are you so bitchy these days? You’re just mean.'
