Khloe Kardashian loves being an aunt. The Keeping Up With the Kardashians star proved that on Friday night, when she spent the evening hanging out with her nieces, Penelope Disick and North West.

Penelope is the daughter of Kourtney Kardashian and Scott Disick. North is Kim Kardashian and Kanye West’s little girl.

Not one too covet all her fun, Khloe Kardashian happily shared photos she took of herself with the precious little girls via social media.

During this photo, the three were watching an animated film called The Book of Life.

There are huge advantages to growing up in a big family. One of those advantages to the littlest family members is having lots of aunts and uncles. Khloe Kardashian certainly takes her duties as an aunt quite seriously.

Khloe has also been stepping up to the plate and helping out sister Kourtney Kardashian in the wake of her split from Scott Disick.
