As the feud between Rob and Kim Kardashian continues to heat up, more theories are emerging as to what caused Rob to fire the first shot.

As you’ve probably heard, Rob compared Kim to “the b-tch from Gone Girl” in an alarming Instagram post that he has yet to delete. (It’s currently the only post on his page.)

It was clearly an act of war, and it seemed to come out of left field. Just a week earlier, Rob turned 28 and all of his sisters (including Kim) posted fond birthday wishes on social media.

So what set Rob off? Well, sources say the bad blood between him and Kim has been bubbling just beneath the surface for years, and as is so often the case with sibling rivalries, it can be traced back to their mother. 

“Whenever Kim gets mad at one of her siblings for not showing up at one of her events or gets in an argument with someone, momager Kris is always dispatched to smooth things over,” a source tells Radar Online.

“Kris is the ultimate puppet in Kim’s world according to Rob. Kris is at Kim’s beck and call, and she goes to great lengths to make sure Kim’s world is perfect. 

“The times that Kris does spend with her other adult children, Kim gets very jealous and will find a way to get her mother to do something for her. Rob refuses to play by those rules anymore.”

Yeah, we can imagine it’s pretty annoying to have the entire world kissing your sister’s sizable ass and then have to watch your own mother get in on the act too.

Of course, all those rumors about Kim making fun of Rob’s weight probably didn’t do much to help their relationship, either.
