Rob Kardashian lashes sister Kim on instagram...

                                                                                                                                                                Rob Kardashian took to instagram today to slam his older sister Kim, whose wedding to Kanye he missed. He posted a photo of the psycho killer character Amy Dunne from movie, Gone Girl and compared her with his sister Kim. For those who have watched the movie, they'll know this is weird. He captioned the pic, "This is my sister Kim, the bitch from Gone Girl." Or is there something else he means by this?
