Robert Kardashian had some harsh words for his older sister Kim Sunday. The only Kardashain brother took to Instagram to slam the reality star.

He shared a picture of Rosamund Pike as Amy Dunne from “Gone Girl.” It’s the scene where Amy is covered in blood after she kills her ex. “This is my sister Kim , the b---- from ‘Gone Girl,” he wrote. Kardashian, 28, who has publicly struggled with his weight, did not add any further information.

Fans quickly liked and commented on the photo. Within three hours, the post garnered more than 61,000 likes and hundreds of comments from his 2.7 million followers.

“Obv a bit of family drama has gone down one time rob pipes up and it's to post this,” one person said. “This is a legit post!!! Family feud!!!” another added.

While it seems like there’s some serious family drama from Rob’s side, the rest of the Kardashian siblings have remained quiet. Kim, naturally, ignored the post and instead plugged Season 10 of “Keeping Up with the Kardashians.”

Sister Khloe, who is the closest to Rob, followed a similar protocol. She ignored the Instagram post and instead plugged the new season of “KUWTK.” She also promoted World Water Day and half-sister Kendall Jenner, who landed a spread in Vogue magazine with fellow fashion model Gigi Hadid.

Even though the other Kardashian siblings seem to have ignored Rob’s message, Perez Hilton noted the 28-year-old unfollowed his whole family on Instagram.

The account seems to be real, since it’s verified and has been tagged by momager Kris Jenner in the past. All the other pictures from the account have been deleted. Rob didn’t add any further insight on his verified Twitter account.
