Now this is a GNO we wish we were at!

Khloe Kardashian proved she's the best aunt ever when she showed off her ladies' night with her nieces on Instagram Friday night.

The black-and-white photos show the Keeping Up with the Kardashians star having a ball with sister Kim Kardashian's 2-year-old daughter North West -- who calls her aunt "Koko Loko" -- and sister Kourtney Kardashian's 3-year-old daughter Penelope Disick.

The girly fun was evident, especially in the pic of Kardashian happily sticking out her tongue as Penelope hops on her back and Nori jumps for joy in the background.

The tiny tots are caught in a quieter moment watching the animated film The Book of Life, but things get super silly again in a video that finds the two bathing suit-clad girls giggling as they chant the word "diamonds."

While Khloe is all smiles during her babysitting gig, her sister Kourtney's relationship with Penelope's dad Scott Disick appears to be kaput. The reality show star moved his belongings out of the house he shared with Kourtney and their three kids, Penelope and her brothers 5-year-old Mason and 7-month-old Reign.

Though 32-year-old Disick has canceled two appearances since the split, he certainly hasn't been moping around alone -- the newly single star just returned to Los Angeles, where he promptly hosted a party.
