We know the Kardashian sisters are close, but now it's official!
Kylie tagged each of her big sisters in the pic, as all of them had a literal hand in the posting. "Friendship bracelets @khloekardashian @kourtneykardash @kimkardashian," Kylie wrote.
The sisters have all been pretty adorable on Instagram together lately, posting selfies together and generally being supportive siblings. In fact, Khloé posted a selfie with Kylie today, with the caption, "The best way to start my day with @kyliejenner."
