To set the scene a bit, Kourtney Kardashian‘s son Mason turns 5 next month on December 14th and it seems the family decided to celebrate a bit early with the party being held Saturday. We’re assuming Kourtney, who’s currently expecting her third child, didn’t want her little guy’s special day to get lost between the holiday’s and the impending birth of Mason’s newest sibling.
And, lucky for us, a ton of pictures from inside the spooky bash have made their way online and have been made available to you in the gallery above.
Special props need to go to Khloe Kardashian, who really got into the spirit of things with a perfect Sally costume. Also on hand were Kendall and Kylie Jenner, along with the family’s favorite makeup artist Joyce Bonelli.
Check out all the photos before you head out and let us know what you think of the extravagant bash in the comments below.
