Mason Disick had a birthday party straight out of a movie on Saturday. Kourtney Kardashian and Scott Disick's son, who turns 5 in December, was surrounded by his mom's famous sisters, including Khloé Kardashian and Kendall and Kylie Jenner, at an early celebration in LA. Complete with Christmas trees covered in spiderwebs, the picture-perfect party captured the mood of Tim Burton's The Nightmare Before Christmas. In a series of Instagram snaps, the group showed off the festive decorations and face makeup, courtesy of artist Joyce Bonelli.
