Kourtney Kardashian, Kendall Jenner and the Rest of the Kardashian Women Attend an All Girls Christmas Party [PHOTOS]

How do the Kardashian women celebrate Christmas? By attending an all-girl Christmas party! Kourtney Kardashian, Kendall Jenner and the rest of the Kardashian clan got into the holiday spirit while attending an annual girl party.

Khloe Kardashian, Kim Kardashian and Kris Jenner were all in attendance at the Shelli Azoff girls-only festive night. The youngest woman in their family, Kylie Jenner was the only Keeping Up With The Kardashian star who wasn't there. As the oldest of the Kardashian sisters, Kourtney was the most festive, as usual.

Kourtney, who is expecting her third child, wore an all-red onsie with a fun Santa hat at the holiday celebration. Throughout the night, her sisters joined in on the party, adding Santa hats to their ensembles as well.

"Pure Love. Just missing @kyliejenner @robkardashian," Khloe wrote on her Instagram with a picture of the four sisters in attendance last night. Kim shared numerous pictures of the party, simply writing, "Christmas Party" with fun Santa, Snowman and Christmas Tree emojis.

In a recent interview, the reality star opened up about her family's annual Christmas card, which didn't happen this year. "I think this is the first year that we're not doing our card, but what we're going to do is, at our Christmas party we have this amazing photo booth so we're going to do like a compilation and do a New Year's card," Kim told Glamour UK.

"We're all going to get together at the beginning of the party and make sure that we all get photos together and do this whole thing. So that's kind of what we came up with, but we're kind of sad, we just couldn't get it together. And where is everyone? Y'know, this one doesn't want to be in it, this one does want to be in it, so who knows?"

In addition to five of the six Kardashian ladies, the adorable holiday party was full of celebrities like Julianne Hough, Gwen Stefani and Kate Beckinsale, according to E! Online. Courtney Cox and designer Jennifer Meyer were also in attendance.
