'We were just brutal': Kourtney Kardashian reveals her biggest fight with sister Kim as teenagers was over clothes as she prepares to head to Australia to launch collection

The Kardashian-Jenner clan seem to be one of the most tight-knit families in Hollywood. 

But Kourtney Kardashian and her younger sister Kim weren't always so chummy.

Ahead of launching Kardashian Kids in Australia in coming weeks, Kourtney told Sunday Style that as youngsters she and Kim would always argue about stealing each other's gear.

'It was probably our biggest fight that we have had. Who stole whose things, especially things that we shared,' she said, later adding, 'we were just brutal.' 

The oldest Kardashian sister, 36, suggested the pair may have felt a little sibling rivalry over their designer threads.

Today, Kourtney often shares cute flashback pictures of herself and her siblings to her more than 18 million Instagram followers, showing the sisters in often coordinated or complementary outfits.

And their early style was no doubt was thanks to their fashion-forward mother Kris Jenner. 

'I remember my mom always kind of matched us, me and Kim and Khloé, and even herself, sometimes,' she told the publication. 

Just last week it was announced that Khloe, 30, will travel to Australia to launch a kid's collection, which will hit Big W stores in August.

She first shared the news on Instagram, writing: 'I couldn't be more excited to announce @kardashiankids is coming to Australia at @bigwaustralia in August!! I'll be heading down under next month to celebrate the launch! See you soon, Sydney!'

Now it has been announced that Kourtney will be joining her sister on the trip.

The Kardashian sisters have amassed a growing business empire including the Kardashian Kollection brand and various other ventures.

But it seems the small disputes between Kourtney and Kim are now between their tiny daughters- Kourtney's daughter Penelope, two, and Kim's daughter North West, who turns two this week.

Kourtney, who has three children with partner Scott Disick - Mason, Penelope and Reign- told Harpers Bazaar US in May that the tots have little disputes over clothes.

'Both of the girls love shoes—last night North was over and they were fighting over shoes in Penelope's closet and they were so cute,' she said. 

'By the end they were sharing and trying the shoes on each other and having so much fun. It reminds me of how Kim and I were when we were little girls.'
