The Kardashian and Jenner sisters all wear matching pyjamas on Christmas Day.

Kendall Jenner has revealed that the reality TV family typically gathers at Kris Jenner's house for the annual celebration, and the showbiz matriarch usually buys her daughters identical nightwear for the big day.

The 21-year-old model - who is the sister of Kylie Jenner and half-sister to the Kardashian girls, Kourtney, Kim and Khloe - shared: ''Normally on Christmas morning, my mom gets us all matching pyjamas that we wear the entire day. Every year is different, but we always match. It's one of my favourite parts of Christmas.''

And Kendall revealed she loves getting her family together for Christmas Day, because their jam-packed work schedules mean they are rarely all in the same place at the same time.

She told Us Weekly: ''I love getting everyone together, we are always all over the place, so it's nice to get everyone in the same room.''

The model said, too, that the Jenners and the Kardashians love to be ''merry'' over the festive season, which includes throwing a party for all of their friends on Christmas Eve.

Asked whether her family have any Christmas traditions, Kendall explained: ''We have an annual Christmas Eve party at my mom's house! We invite everyone we know and eat and drink and actually - be merry!''

Meanwhile, Kendall revealed earlier this year, that despite her glamorous appearance on the catwalk, she used to love dressing up in boys' clothes.

The brunette beauty shared: ''I was a huge tomboy. I had a phase where I wore boys' clothes. I was always hanging out with guys. I've always connected with guys more.''

Kendall credited her attitude to her father Caitlyn, who was known as Bruce prior to undergoing gender reassignment surgery.

She said: ''I've always been the different one.

''I mean, I'm a girl and I like being a girl, but I've just never been into it like they have. I think I get that from my dad. I'd say I'm more of a Jenner than a Kardashian.''
