If you thought the Kardashian sisters were just family, think again! Apparently they’ve formed their own gang now too. Okay, not for real, BUT Kendall Jenner and her big sis Khloe did buy matching black “K Gang” hats. They showed them off on Kendall’s Instagram page yesterday. Don’t worry; they’ve also got one for lil sis Kylie. We wonder if Kim and Kourt got left out?
