Khloe Kardashian spent some quality time with niece North West on Tuesday.

The 31-year-old reality star shared a photo of herself playing laser tag with the 2-year-old on Instagram, writing, "North x KoKo." North's mom, Kim Kardashian, shared a picture of the toddler the next day after praising mom Kris Jenner's holiday decorations.

"She understands who Santa is," Kim wrote of North on her website. "It's going to be so fun with North and [son] Saint and all the kids, watching them open gifts this year! It gives Christmas a new meaning when you get to experience it through your child's eyes."

Khloe was one of many relatives to help Kim and husband Kanye West welcome son Saint on Dec. 5. The reality star gushed about her new nephew during a livestream last week, telling fans the baby is "so cute and perfect."

Khloe is also aunt to sister Kourtney Kardashian's three children, Mason, Penelope and Reign Disick, and sister to 28-year-old Rob Kardashian. She encouraged her reclusive brother with a motivational post Monday, calling him her "one and only."

In addition to E! series "Keeping Up with the Kardashians," Khloe will star on FYI network talk show "Kocktails with Khloe" come Jan. 20. The television personality previewed the project in a behind-the-scenes video posted Tuesday.
