In one of Kim's Snaps from the party, she said "I know what you guys all really want to see" and showed Khloe rubbing her fringe-and-sparkle-covered stomach.
During the glam bash, Kardashian was finally ready for her close-up-with a gray fur coat draped around her shoulders and her platinum locks pulled into a perky ponytail-and made a cameo on sister Kim's Snapchat.
Kim had her hair relaxed and blonde, parted in the center, while posing with a number of happy party-goers.
The party was otherwise notable because Kris Jenner invited both Scott Disick and Kourtney's current boyfriend Younes Bendjima - and both of them showed.
Even Santa Claus himself took time from his busy present-delivery schedule to call in at the annual extravaganza held at Kris' American pad, much to the delight of Kim's daughter North.
Also seen in the video is Kim, reclusive brother Rob, and the teeny tiny Kardashian kids.
Khloe meanwhile lamented not drinking due to her pregnancy. There might be some hard feelings between Caitlyn and her ex-wife stemming from the Olympian's controversial memoir published earlier this year, The Secrets of My Life.
