Doesn't seem like Rob Kardashian has much brotherly love for his sister Kim Kardashian. The former reality star, 28, deleted all images from his Instagram account and replaced them with a single still from Gone Girl. He captioned the picture, of Rosamund Pike as murderous psycho Amy Dunne, "This is my sister kim, the b***h from Gone Girl,,,"
It's not clear whether the post is intended to be a joke, but considering the only Kardashian brother's strained relationship with his family in recent months, it has certainly raised some eyebrows.
Things appeared to be fine between the siblings last week. Kim, 34, posted a throwback shot with her younger bro on Instagram, writing, "Happy Birthday to my one and only brother Robbie!!!! I remember this Vegas party of yours like it was yesterday! I love you so much and can't wait to share so many more memories with you! Kiki Riki!!!!"
Rob is one of the more reclusive members of the otherwise exposure-hungry family, mostly opting out of the family's reality TV franchise and staying out of sight of paparazzi. In 2013, he went through an ugly split with pop star Rita Ora and accused her of cheating on him with multiple men.
