Kourtney Kardashian lets her children decorate their own individual Christmas trees.

The 'Keeping Up With The Kardashians' star has revealed she bought four trees for her house this year so her children - Mason, seven, Penelope, four, and Reign, two - can design their own for their rooms.

She told Vogue magazine: ''We all go to a lot together and have the kids pick out their own trees for their bedrooms; they can decorate them however they want. It's a perfect spot for homemade decorations and allows them to be creative and have fun with it and do something all together as a family.

''Christmas morning takes place at my house and my entire family comes here, so I also have the responsibility to make it special for all of them. And I love doing it! It's still very festive over here. Christmas music on from the second we wake up until bedtime.''

Meanwhile, the 37-year-old television personality previously revealed she will be hosting the family's Christmas brunch, where she'll hold a big buffet for her relatives.

In a post on her app, she said: ''My dining room is one of my favourite rooms in my house. I use the space to entertain - it's perfect for when I have the whole family over ... I'll have a big buffet in the kitchen and set up the table for everyone.''

And Scott Disick is likely to be there for the festive celebrations as they have reportedly got back together.

An insider shared: ''Their love for each other never went away. He's been trying to win Kourtney over for a while now, but his constant partying was a huge issue. He's been spending a lot more time with Kourtney and the kids and proving himself to show that his family is the priority ...

''He's doing his best to keep himself in check. Kourtney is definitely the reason for that. He still has his own place, but he loves her. He's always loved her and wanted his family back together. They're best friends - that's never changed, even when things were rough between them ...

''Scott has just been over the partying. He got sick of it and decided to clean up his act. He was having people over at his house to party until 6 a.m. all the time, and he hasn't been doing that either.''
