Family always has your back!

Khloe Kardashian and younger sister Kendall Jenner have been spending a lot of time together recently, and the pair showed the world just how close they've become by sharing a new Instagram pic of themselves wearing matching "K Gang" hats.

"K GANG! Don't worry Kylie, we have one for you too," the 18-year-old aspiring model captioned the snapshot. That's nice she remembered to include her other sibling!

Lamar Odom's estranged wife is going through a tough time since filing for divorce last week, and she tweeted an ominous message today that seems to reference her split.

"This, in and of itself, is heartbreaking and torture to my soul. Please, I don't need the extra rumors and BS right now," she wrote on her account.

Meanwhile, their other sister Kim was busy sharing some pics of her own! The new mom attended fiance Kanye West's concert last night with pal Larsa Pippen, and wasn't the least bit shy about showing off her hot post baby bod.

"Chicago with my sis @larsapippen," she captioned the photo.

Talk about keeping up with the K clan!
