VIDEO : Khloe Kardashian Celebrates Christmas With Her Niece and Nephew

After a big, rockin' Christmas party at mom Kris Jenner's home, the rest of the holiday was child's play for Khloe Kardashian. The 31-year-old Keeping Up With the Kardashians star spent some quality time with her niece and nephew, North West, and Mason Disick, as seen in photos posted on her Instagram page on Friday, Christmas Day. Khloe shared a pic of herself and the latter, sister Kourtney Kardashian's eldest of her three children, sporting adorable holiday-themed onesies and giving the peace sign while posing in front of a Christmas tree. She later shared pics of North giving her a makeover...as best as a 2-year-old can.
