The Keeping Up With the Kardashians star then turned the camera on some of the night's guests, including sister Kendall, who was all dressed up in goth-like attire, complete with dark lips, a skin-tight latex dress, fishnet stockings and sky-high platforms.
As for the party itself, the social media maven's house was completely transformed for a creepy dinner. Guests were led through dimly lit hallways to their dining area, which was decorated with a skull centerpiece and dark red roses.
From there, Jenner's ghostly guests feasted on a Halloween-themed menu of rotten tomato soup, potion pear salad, penne with creamy blood sauce, and a chocolate ice cream casket while the theme song to the 1978 film Halloween played in the background.
There were also many treats to be had, including a table full of Halloween-themed sweets, floating-eye cocktails, and margaritas served in syringes.
Jenner wasn't the one feeling a little skeletal on Friday night. KUWTK's executive producer, Ryan Seacrest, also donned a skeleton costume as he attended George Clooney's annual Casamigos Tequila Halloween party.
