ROB Kardashian has launched a scathing attack on his sister Kim Kardashian on social media.

After a long absence from Instagram, the 28-year-old today posted an image of Rosamund Pike’s character from Gone Girl with the caption, “This is my sister kim, the b**ch from Gone Girl”.

In case you haven’t seen the movie, the character of Amy Dunne has been described as “one of the most disturbing female villains in movie history” and a “cold, calculating psychopath”.

It’s no secret that Rob and Kim aren’t on great terms.

He’s been keeping a low profile since he bailed on Kim’s wedding to Kanye West in Florence in May last year.

At the time, there were reports he fled back to the US after a huge fight with Kim about his weight.

On the weekend, Khloe Kardashian opened up about her brother’s problems, telling Wonderwall, “I just feel, especially over the last year, Rob has become very introverted and has a kind of social anxiety”.

The Kardashian brother decided to bail out on his sister's wedding.

“He’s definitely not at his happiest place that he once was, and I know he can get to that happy place and he will.”

Even though his relationship with Kim has clearly soured, Khloe told the site she’ll always be there for her brother.

“We all kind of get to a place where you don’t know where to go in life or whatever, so I think it’s important for him to know that he always has people to lean on and it’s not unnatural for people to not know even where to begin.

“It’s a growing process. ... I will always be his No. 1 supporter.”
