4. Lea Michele & Naya Rivera in Glee
According to rumors, two of the Glee cast members, Rivera and Michele didn’t get along in real life. Their dislike for each other allegedly sparked a confrontation on the set of the dramedy musical and Michele wanted Rivera off the show. Michele obviously held some power because Rivera was written out of the final two episodes of Season 5, to which Rivera decided that she would not be returning as a series regular in the six and final season of Glee. Eeek!
