Rob Kardashian's rivalry with big sister Kim shows no sign of slowing down.
The reality tv star (26) has pulled back from the show and the spotlight in the last year, but seems to have taken his difficulties with Kim to new levels.
“This is my sister kim , the b***h from Gone Girl,,, (sic),” he wrote in a caption attached to an image of Rosamund Pike in character as Amy Dunne, a psychopathic, murderous persona, he wrote on his Instagram earlier this week.
The two have a well documented history of fighting with one another, which has played out on Keeping Up With the Kardashians and on social media.
"He feels that she has destroyed their family and he doesn't even know her anymore," an insider told Radar Online. "Honestly, he doesn't even want to know her anymore."
"She is dead to him and there is nothing that she can really do to redeem herself," the source told 'Radar Online.'
