The latest news involving Rob Kardashian's Instagram post has been making the rounds on the internet as of late.

This is after the 28 year old went back to Instagram after a long hiatus, and posted a photo of actress Rosamund Pike during her bloody scene at her recent film with fellow actor Ben Affleck, "Gone Girl." Rob compared Pike's character to her sister Kim, as he captioned the photo with, "This is my sister Kim, the b**ch from Gone Girl." 

Numerous lifestyle publications picked up the news quickly, and while they say that the photo was not to be taken seriously as Rob allegedly just has a different sense of humor that not everyone can relate to, his mom Kris Jenner seems to think otherwise.

According to Hollywood Life, Kris is pissed at her son, and thinks that the whole thing is immature and is not considering it to be something funny, as how most people are considering it to be. She is reportedly calling him out, telling him to apologize to his sister.

"Instead of seeing Rob's Instagram as a cry for help Kris is pissed that Rob is taking to social media to bash the family," said a source to the website cited above. "She has told Rob to apologize to Kim but he has refused which is only getting Kris more heated." 

As previously reported, Rob has been undergoing a big amount of stress lately due to his overweight body. Kim, who stars in "Keeping up with the Kardashians," can be watched in the series to give her younger brother some tough love, by letting him be and not helping him out when he asks for it.

Hollywood Life also reported that Rob has allegedly unfollowed on Instagram the rest of his family.
