5 WWE backstage arguments you probably didn't know happened 

#1. Randy Orton and WWE Universal Champion Roman Reigns

Randy Orton and Roman Reigns are two of WWE's biggest stars at present. Their pushes to the main event level have made both stars larger-than-life characters.

Back in 2013, when Reigns was still coming through the ranks in WWE alongside Seth Rollins and Dean Ambrose in The Shield, he crossed Randy Orton after the duo argued over a botched spot in a live event match.

According to Dave Meltzer of The Wrestling Observer, this led to massive heat on Roman Reigns early in his career.

"There was heat on the Shield in recent weeks. It was said that Rollins and Reigns were the two the office was upset with... Another WWE source said the issue with Reigns was that there was a house show tag match which Reigns and Randy Orton were in, and they botched up a spot and got into a shouting match about it backstage. A guy in Reigns' spot arguing with a guy in Randy Orton's spot is a great way to get massive heat on you." Said Meltzer.

This heat doesn't seem to have affected Roman Reigns' career, since he is the current Universal Champion and was destined to become a star in WWE.
