Rob Kardashian Slams Kim Kardashian In 'B**ch From Gone Girl' Instagram Post Beef, Kanye West Defends Wife?

"Keeping up with the Kardashians" reality star, Robert Kardashian called out his sister Kim Kardashian for being a "B**ch" from the movie "Gone Girl."

Sunday night the only male Kardashian confused fans after he posted an Instagram photo of Gone Girl's Rosamund Pike's character, Amy Dunne, who tries to frame her husband of her murder after finding out about his affair, but backs out and comes back home bloody.

It's unclear what the exact cause of their drama was, but it isn't the first time the youngest Kardashian slammed his sister in public and even ditched her 2014 wedding over his depression from his recent weight gain.

In 2011, the siblings got into a screaming match during a KUWTK episode after she called him out for being jobless during their family trip to Bora Bora despite his other siblings' career successes. Robert retaliated by calling Kim a "wh***" for her sex tape success with singer, Ray J.

Kim's ex-husband, Kris Humphries tried to stand up for his wife telling Robert, "How you deal with your sister, like in front of me, you're not gonna call her that in front of me," he added, "I don't want to be the guy that takes a knife and kills my sister's boyfriend."

Does Robert really despise Kim?
