Watch North West Sing a Duet With Sia at the Kardashian-Jenner Christmas Eve Party

North West had a very merry Christmas, partially thanks to singer Sia. North shared lots of videos on TikTok from the famous Kardashian-Jenner Christmas Eve party, including clips of her, her mum Kim Kardashian, and her sister Chicago getting ready for the event. But in one clip in particular, North, 9, sang at the star-studded bash alongside Sia! The pair turned Sia's song "Snowman" into a duet. Sia was standing in a clear box, and North snuggled up to her side to sing along with her. She wrote over the video simply, "Christmas time."

After the event was over, the Kardashian-Jenners all took to Instagram to share photos from the Christmas bash. Kim posted a slideshow of her four kids — North, Saint, 7, Chicago, 4, and Psalm, 3 — alongside their 6-year-old cousin Dream. Kim also shared photos with her sisters Kourtney, Khloe, Kylie, and Kendall and their mum Kris. Some of the photos showed off the party decorations, which featured bright red Christmas trees and red balloons attached to the ceiling.

Kim has never said if North wants to pursue music longterm, but she has posted quite a few videos of her daughter singing and dancing. Earlier in December, North and Kim's TikTok page posted a video of North doing the Wednesday Addams dance. In November, the account posted a video of North dancing along with Lizzo backstage at her concert.

But the family's musical social media moments aren't always so blissful. In August, Kim posted a video to Instagram of her singing along to Bruno Mars with North and her cousin Penelope Disick in the backseat. At first, they're all singing together, but when Kim starts recording North yells at her to delete it and stop singing.

The annual Kardashian-Jenner Christmas Eve party is a longstanding tradition for the family. This year, the event was held at Kourtney and Travis Barker's home.
