On screen, these pairs of co-stars seemed to get on famously, but behind the scenes, things were anything but friendly. You'll be shocked by some of these famous pairs from movies and TV who just didn't get along in real life!

It turns out that Lea Michele and Naya Rivera's actual relationship was pretty close to the relationship that their constantly feuding characters on Glee had. Behind the scenes, there were rumors that they didn't get along, reportedly due to Naya being jealous of Lea and all the attention she gets.
