Kim. Insiders are agreed that Rob’s apparent new romance with Blac Chyna has largely to do with his desire to hurt his famous sisters. Having famously compared Kim to Amy Dunne the sociopath portrayed by Rosamund Pike in Gone Girl Rob has also closed himself off from his siblings as he struggles with his weight gain, diabetes diagnosis and depression. Rob likes [Blac] and seems to think it’s mutual. It’s just hard to take things seriously since obviously both share a lot of anger toward the [Kardashian-Jenner] girls, a source told People. They have both had a lot of drama with Kim. Rob really seems to get a kick out of all the drama that he is causing.
