Maybe he was just hacked?
On Sunday morning, Rob Kardashian's Instagram account posted a photo comparing his sister Kim Kardashian to "amazing" Amy Dunne in Gone Girl.
Rosamund Pike was nominated for an Oscar for her portrayal of the manipulative Amy in Gone Girl, but we don't think Rob meant this as a compliment. Hence the comment, reading: "Come on bro, that's your sister."
The post is captioned, "This is my sister Kim, the b**ch from Gone Girl." If you haven't seen the movie, here is your spoiler alert!"
This photo shows Amy as she returns home covered in blood, after an entire plot of scheming and faking her own death to get revenge on her cheating husband Nick, played by Ben Affleck.
Just recently, Kim, 34, showed no signs of bad blood between herself and Rob. She posted a message for her brother on his 28th birthday on March 17, writing: "Happy Birthday to my one and only brother Robbie!!!! I remember this Vegas part of yours like it was yesterday! I love you so much and can't wait to share so many more memories with you! Kiki <3 Rikki!"
Though he has 2.7 million followers, Rob is not following Kim or any of his other family members on Instagram.
