Khloé Kardashian clearly LOVES being an aunt!
The 31-year-old shared photos of nieces Penelope Disick and North West as well as nephew Mason Disick having a ball in some festive PJs on Christmas day.
In a particularly adorable moment, two-year-old North, who just became a big sister, applies lipstick to the reality star's face. Looks like she inherited mom Kim Kardashian's love of makeup!
