Kardashian-Jenner Christmas Party Photos: Here's What Went Down

The Kardashian-Jenner family went all out for this year's holiday season, throwing a massive red-and-white-themed Christmas Eve party in California Saturday night.

The whole family gathered together at Kourtney Kardashian's Calabasas mansion for a night of partying and enjoying Christmas snacks and grownup beverages, according to TMZ.

The 43-year-old Poosh founder splurged on the decorations, which included huge window-to-ceiling-high red Christmas trees, bright lights that surrounded the home and a huge ball pit for kids to play in.

Kim Kardashian, Khloe Kardashian, Kris Jenner, Kylie Jenner and Kendall Jenner were all in attendance along with relatives and close friends, as seen in various Instagram Story posts on their respective accounts. It's unclear whether Travis Scott, Tristan Thompson and Kanye West were invited to the bash.

On Sunday, the 67-year-old momager took to Instagram to share photos of the lavish party, including a snap with her daughter Khloe, who wore a sleeveless bright red dress and a diamond necklace for the occasion. Kris, for her part, rocked a red long-sleeve ruffle dress with a huge ribbon on the front.

Cici Bussey, Malika Haqq and Faye Resnick were also in the photo.

Other photos showed more of Kourtney's red-and-white themed decorations, including the candle-lit tablescape, the ceiling filled with red balloons and a fireplace surrounded by red Christmas trees.

As for the other Kardashian-Jenner sisters, Kylie, 25, donned a figure-hugging black and nude dress. Kendall, 27, also wore a dress that showed off her curves, but unlike her younger sister, her sparkly red sleeveless dress was on theme.

Meanwhile, Kim, 42, wore a silver slim-fit gown with a high slit on the side. She also showed off her new hair color, returning to her dark brown hair after months of rocking bleach-blond locks. Their eldest sister, Kourtney, wore a long sheer white dress.

But aside from the lavish decorations and the family's fabulous looks, there was more to the Christmas Eve blowout that made this year's festivities stand out.

The family surprised their guests with a performance from Sia, who is known for the chart-topping singles "Chandelier," "Titanium," "Cheap Thrills" and "Elastic Heart."

In the Skims founder's Instagram story, she posted a clip of the 47-year-old Grammy-nominated musician performing the 2014 hit "Chandelier." She also posted a video of Sia performing a duet of her Christmas single "Snowman" with Kim's 9-year-old daughter North.

A longer clip of the surprise performance was posted on the mother-daughter duo's TikTok account. The video has already accumulated 2.6 million views as of writing.

The Kardashian-Jenner family has thrown Christmas Eve parties for years. During the earlier years, their mom Kris hosted the extravagant bash, but in 2019, Kim and Kourtney decided to pick it up from her.
