PIC: Rob Kardashian Just Attacked Sister Kim In His Latest Social Media Post

It’s been long documented that Rob Kardashian and sister Kim have had a rocky relationship, but the reality star siblings’ feud is under fresh scrutiny after a social media post today. Rob, who has battled with the media attention and scrutiny over his weight and his family’s TV show, hit out at sister Kim, with an Instagram post implying his sister was psychotic. Referencing the thriller book and film Gone Girl, Rob posted an image of main character Amy Dunne covered in blood to his account, complete with the caption: "This is my sister kim , the bitch from Gone Girl,,,"

This isn’t the first time Rob and Kim have come to blows, with the 28-year old failing to attend his sister’s wedding to Kanye West after boarding a flight home after a “family feud”. While the details surrounding the row are not known, sources reported that an argument broke out between the siblings during a lunch at designer Valentino's Château de Wideville in Crespières, France after he branded her wedding plans ''superficial bulls**t''. We can’t see this latest post helping heal that rift anytime soon…
