It's a fortnight since Halloween and more than a month until Christmas, but that didn't stop the Kardashian clan going for a spookily festive fancy dress theme this weekend.

Khloe Kardashian has been sharing snaps of herself with half-sisters Kendall Jenner and Kylie Jenner - along with an amazing pic of Kourtney's son Mason, whose birthday they were celebrating, in similar make-up.

The party was themed around Tim Burton's modern classic The Nightmare Before Christmas, with celeb make-up artist Joyce Bonelli giving the sisters and kids a stunning transformation into characters from the movie.

Khloe, who was almost unrecognisable, wrote on Instagram: "Kourtney pulled a 'mean girl' move on me and had me dress like Sally from The Nightmare Before Christmas while everyone else was mad chill."

Confusingly, Mason's actual birthday isn't until 14 December.
