North Sings with Sia — Check Out all the Glam

The nine-year-old daughter of Kim Kardashian and Kanye West was having an absolute blast all night long, sharing lots of fun and silly moments on her joint account with mom Kim, but she was radiating while joining Sia on “Snowman.”

The two looked like they were the next exclusive release from Mattel’s Barbie line, standing together and singing from inside a giant pink box with a Christmas tag on it.

While Sia was in all white with an ornate matching headpiece, North was in all black. Most of the Kardashian-Jenner’s were in matching monochromatic, with favorite colors included decor-matching red and Kim’s glamorous and shimmery silver.

Kim matched her glamorous style with a return to her black hair, as well, after spending some time blonde. Khloe, though, was keeping blonde alive as she gave fans a quick tour of the lavish Christmas Eve bash.

“You guys, I’m like the first one here because I was so excited,” she exclaimed as she offered a sneak peek of the layout before guests arrived. It included a miniature See’s Candy shop a ball pit and incredible decorations.
