Working for a celebrity might seem like a dream come true, but for many employees it ends up being a nightmare. Rihanna is known for being a diva, and apparently that extends to how she treats her staff. Lady Gaga might come across as a kind person, but she’s incredibly demanding and requires her staff to be on call 24/7. Bruce Willis is a great actor, that even other actors can’t get along with on set. Many celebs get away with their bad behavior, but Megan Fox’s ended up getting her fired and blacklisted from Hollywood. Lea Michele has a reputation for being a diva on set, but apparently she takes that attitude with her when she goes out to eat as well. In the comment section, make sure to tell us which one of these celebrities you would hate to work for.
