It may come as a surprise to see the Kardashian sisters coming to blows in the new trailer for their upcoming reality show Kourtney And Kim Take Miami.

For as fans of their original show Keeping Up With The Kardashians know, the only thing the girls like more than making and spending money is a bit of drama.

The sisters come to blows in the brief 30 second clip – although there’s no explanation as to why they are fighting.

With their hair flying around, Kim and Kourtney Kardashian are seen engaging in what can only be described as a cat fight.

The trailer promises more of the winning formula which has made the sisters such a hit with fans – with scenes featuring Kim and Kourtney Kardashian sunning themselves in bikinis, Khloe in the bath with husband Lamar Odom, and of course an explosive fight.

The trailer also shows the reality stars water skiing and drinking with pals.

Filming on the series has now wrapped, with the sisters heading back to Los Angeles for Christmas.

Kim Kardashian tweeted: “I am so glad to be home for the holidays!!

“I loved spending time in Miami but LA is my home and I am really looking forward to spending some quality time with my family.”

And she promised: “Our time in Miami has come to an end and I can’t wait to show you all what we got up to while we were down in Miami when the show premiers in January.”

Luckily for fans they don’t have long to wait – the new show is set to air on the U.S. in early January.

Meanwhile Kourtney Kardashian has been sharing her plans for the holidays.

She attends a huge family Christmas party thrown by her mother Kris Jenner every year, but she is keen to start her own traditions with boyfriend Scott Disick and their children Mason, three, and Penelope, five months, away from her wider family.

She said: “I think it’s important to continue some of the family traditions, like the Christmas party, but to make it my own with Scott and the kids as well.

“Last Christmas Eve, we all had our own friends over and decorated gingerbread men, I want to do that again this year.”

However, Kourtney Kardashian, 33, will still be heading to Kris Jenner’s party because of all the tasty treats which will be on offer.

She added: “At my mum’s party, she has so many different things to try. I eat a little bit of everything, but not so much that I feel guilty. Everything in moderation.”
