We’ve been given a glimpse of the pair’s close relationship (and their bickering) on Keeping Up With The Kardashians over the years – but now Kendall’s opened up more on her website.
In an emotional post entitled Growing Up With Ky, the 20-year-old writes: ‘It’s funny – growing up, Kylie and I were the terrible twosome!
‘We were so rebellious and adventurous. We would run around all day long and just do stupid things with each other. I couldn’t imagine growing up any other way.
‘It was awesome having someone so close in age to me – we could relate to one another.’
It’s probably no coincidence that Kendall’s post came days after a clip from the new series of KUWTK showed her and Kylie, 18, having a HUGE argument.
The fracas took place before the ESPYs in July, where their father Caitlyn Jenner was honoured with the Arthur Ashe Courage award.
They were getting ready at Kylie’s house when Kendall realised she hadn’t brought an outfit to change into for dinner after the show. A major dilemma, obvs.
Kendall told Kylie that she’d borrowed one of her gowns, before Kylie angrily replied: ‘You know it is not necessary to borrow my s***.’
This led Kendall to call her sibling ‘the biggest f***ing b**** she’s ever met’ and a ‘c***’. OUCH. So it’s clear that things can get more than a little heated between them.
But Kendall has played the incident down, continuing: ‘Now, we’ll occasionally argue with each other and say horrible things, but definitely not on the level that it used to be, lol.
‘We’ve always remained close, but over the years the two of us have just matured. We’ve really kind of found our own identities, which I think was important to us both.
‘For years we were really stuck as a duo and now we’ve truly become our own people.’
Aw. Well it seems they’ve forgiven each other, eh?
