The tagging of her in the photo is also a nice touch, just in case she tries to pretend she didn't see the photo.
Siblings fight, everyone knows that. In fact, some fights between siblings can get pretty rough but at the end of the day, that's family. But when your sister is (unfortunately) one of the most famous people on the planet, that fighting becomes a bit more public. Which is probably what Rob Kardashian was hoping for when he published this picture of Rosamund Pike's character from Gone Girl *spoiler* covered in the blood of a man whose throat she slit open, with the accompanying caption of "This is my sister kim , the bitch from Gone Girl,,,(sic)"
According to TMZ, Rob had been MIA on social media for a few months but reappeared to post this just after he unfollowed his entire family on Instagram (which he has since undone).
Let's get real here, Rob's a Kardashian at the end of the day, and we know how those Kardashians like to make a splash with some nonsense. And you can bet he's got a lot of angry voicemails and missed calls from Kris Jenner this morning, but look here we are talking about them, which makes everyone a winner... except us.
