In fact, they’ve gone one step further. In a clip from the new season of Keeping Up With The Kardashians, the pair get into a serious fight. EEK.
The drama takes place before they head out to the ESPYs, where their father Caitlyn Jenner was honoured with the Arthur Ashe Courage award.
They’re getting ready at Kylie’s house, but unfortunately 20-year-old Kendall is having a bit of a wardrobe disaster.
She tells her sibling that she doesn’t have a second outfit to wear after the show – and that she’s taken one of her dresses to change into.
That won’t be a problem, right? Well, it seems it is. Kylie asks her assistant: ‘Is Kendall ready? She’s not taking any of my clothes, right?’
Over the upstairs banister, her assistant answers: ‘Just one brown random dress.’
Kylie seems pretty annoyed, pacing around the bottom floor (in that infamous Shady Zeineldine gold floor-sweeper) while Kendall struggles to sort out her clothing options upstairs.
She then exclaims: ‘She can’t wear that. That’s one of my favourite brown dresses.’
Kendall appears at the top of the stairs, sporting a sheer Alexandre Vauthier number. She isn’t going to take Kylie’s refusal lying down, shouting: ‘I’m not going to dinner likes this. I can’t sit.’
Unfortunately, Kylie is adamant, replying: ‘So, you can go have someone go grab clothes from your house. Why would you want to wear something from my closet when you can have…’
Kendall interjects: ‘Because I can’t. We’re going straight from the show.’ Kylie retorts: ‘Yes, you can have someone drop s*** off.’
This is where things get majorly heated. Kylie adds: ‘You know it is not necessary to borrow my s***,’ before Kendall angrily retorts: ‘You’re just literally the biggest f***ing b*tch I’ve ever met.’
She then comments to Kylie’s dogs: ‘I’m sorry your mom is such a c***.’ Um, wow.
Thankfully, the pair seemed to have made up by the time they posed on the red carpet together. Oh, sisters…
