Anyone who has ever watched Rosamund Pike in last year's film, "Gone Girl" would know that the character she played is probably the worst possible nightmare to have for a wife - a b**ch from hell, so to say.

Here come's Rob Kardashian calling his sister Kim the B-word on Instagram, saying that she's the "b-ch from 'Gone Girl'."

Rob has been MIA from social media recently, and photo of Pike's Amy Dunne, covered in blood after she killed an ex-lover, was his comeback.

Of course, the bigger question is why Rob would choose to post a photo of the bloodied version of Amy instead of a relatively normal one, and news and entertainment sites like The Hollywood Life are wondering if he thinks his older sister is a psycho like Amy. His caption is not even neutral, it stated, "This is my sister kim , the b-ch from Gone Girl,,,"

This is also questionable coming from Rob, considering that he decided to skip his sister's wedding to rapper Kanye West last year, and he has been distancing himself from the entire family, even missing his mother, Kris Jenner's annual Christmas Eve bash last year.

However, according to the Huffington Post, the photo may posted by a hacker, because aside from the shocking photo, it appeared to be the only one in Rob's account, all of the previous ones having been erased. That's not all that Rob (or his hacker) did, however, as apparently, Kim's little brother unfollowed all of his family members in the photo media site.

The post that attacked Kim also does not fit in with the events of the Kardashian clan, as according to E! News, a few days ago, Rob received a lot of support from his family for his birthday, with Kim sharing a throwback picture of the two of them together in Vegas, captioned, "Happy Birthday to my one and only brother Robbie!!!! I love you so much and can't wait to share so many more memories with you!"

Khloe also wrote a touching message of support for Rob, saying, "Never will I ever meet another man as great as you! I know this is the year where you will find your happiness again! I will be right by your side, holding your hand, every step of the way!!! I adore you my one and only brother!!"

With these seemingly happy and supportive posts from his sisters, do you think Rob's Instagram post is all in good fun, or was his account hacked, or do you really think there's something going on in the Kardashian family that may indicate they are more messed up than people think?
