Kim is the hardest Kardashian sister to buy Christmas presents for.

The 31-year-old reality star's sisters Khloe, 28, and Kourtney, 33, find it difficult to buy her gifts over the festive period, despite the fact she does drop a lot of hints, but they think the rest of their family's tastes are easy to guess.

Kourtney said: ''[Kim] is the hardest to buy for as she does have everything. My sister Khloe and I get each other things for our homes as we're both into interiors. My mum [Kris Jenner] is easiest to buy for as she loves everything. But everyone in our family makes a wish list, in fact Kim is good about hinting.''

Kris, 57, appears to be the most Christmassy member of the family, throwing a festive theme party to kick things off for the rest of the family.

Kourtney added: ''My mum has a huge Christmas Eve party - everyone gets dressed up and we have food and music. Santa Claus comes too, and there are lots of arts and crafts for the kids - it's a lot of fun. The next day we're still up at my mum's house and she makes us get up at 6am to open our presents in out pyjamas.''
