The 2-year-old spent Christmas Day experimenting with lipstick, giving her aunt, Khloe Kardashian, a makeover.
"I'm North's first makeup client," the 31-year-old reality TV star captioned the sweet pic.
In another photo posted just a few minutes later, Khloe showed off the finished product, writing, "Major side eye."
Khloe also spent quality time with Kourtney Kardashian's eldest children, Mason, 6, and Penelope, 3.
"Merry Christmas Mase x KoKo," Khloe captioned an adorable snap of her and Mason in holiday-themed onesies.
She later posted two back-to-back photos of Penelope sitting on her lap in front of a Christmas tree, which was followed up with a laughter-filled video.
While Kourtney's youngest child with Scott Disick, 1-year-old son, Reign, didn't make an appearance in Khloe's Instagram snaps on Friday, he did make it on to the Kardashian Christmas card.
Kim gave birth to North's brother, Saint West -- her second child with husband Kanye West -- earlier this month.
Just 10 days after giving birth, Kim revealed she had already lost 17 pounds during a livestream with Caitlyn Jenner. Hear more in the video below.
