Rekindling an old feud? Last year Rob Kardashian posted a since-deleted pic on Instagram comparing Kim Kardashian to a blood-covered Amy Dunne from Gone Girl, according to Daily Mail. He captioned it, “This is my sister Kim, the b**** from Gone Girl.”

At the time, Rob posted the shot because he was mad at Kim and thought it was funny. Kim failed to see the humor in being compared to the psychotic character, however, telling her sister Khloé in an episode of KUWTK, “You get purple hair and I get the girl from Gone Girl!”

Now, with a pair of socks, Rob may just be stirring up trouble.

He sent Kim a pair of purple and gray Gone Girl Socks ($15) by his company, Arthur George, that have the words “GONE” and “GIRL” on the bottoms.

The official account for Arthur George posted a video of Kim receiving the pair, and let’s just say her reaction is not what we thought.

Kim seems to have gotten over their old feud, because in the video she says, “How cute, my brother made me socks! Thank you, Arthur George.” Glad to see the pair have buried the hatchet.

What do you think of Rob’s gesture? Tell us @BritandCo!
