Occasionally, we all have a rough day, and it’s possible that some of the superstars who are infamous for being unprofessional are just guilty of one solitary event. This list, however, includes performers who have earned a reputation for being difficult to deal with, and unprofessional throughout the years, to the point that it has harmed their chances of landing assignments.

Russell Crowe

Without a question – Russell Crowe can act. He has built a name for himself not just as an actor, but also as a result of his wild antics over the years. These have included anything from threatening to murder movie producers over the phone to drunken brawls and abusing people on Twitter. George Clooney was reportedly enraged when he called him a sellout for starring in TV ads. Clooney answered with the following statement: “Dude, the only people who succeed when two famous people are fighting is People magazine. What is wrong with you?”

2. Katherine Heigl

One might easily sympathize with Katherine Heigl, a once-promising actress who found success with Grey’s Anatomy and the Judd Apatow comedy Knocked Up. Heigl, on the other hand, formed an unprofessional reputation of herself for being vociferous and critical of the projects on which she has worked. She reportedly branded the aforementioned Knocked Up as sexist and chastised Grey’s Anatomy, the program that launched her career. It didn’t help that Heigl’s project selections were poor, with flops like The Ugly Truth and Killers doing little to further her reputation.

3. Jennifer Lopez

There’s a story going around that J Lo is a nightmare to deal with. She appears to be on the verge of flying off the handle if her expectations are not fulfilled before she arrives at work. J Lo has certain expectations of her aides, according to a source who spoke to Scene Queens. The person must, among other things, be elegant under strain, have a thick skin, and be resourceful in other nations. They must also be able to travel at the drop of a hat and acclimatize to each new place.

4. Charlie Sheen

This list would be absolutely incomplete without the mention of Sheen. It’s no wonder that he has a reputation for being a challenging actor to deal with. Sheen is well-known for his outlandish behavior, drug usage, and excessive partying. His marriage to Denise Richards didn’t last long, and it didn’t end well either. Because of his erratic conduct, he was finally kicked from Two-and-a-Half Men. Charlie Sheen is now well-known for being a wacky actor who can’t seem to secure nearly as much work as he used to and is now more well-known for saying odd things.

5. Beyonce

After her absurd demands during the 2013 Super Bowl, Beyonce was awarded the “Most Difficult Celebrity”. Her unprofessional expectations included having water frozen to 21 degrees and delivered only with a $900 titanium straw. She needs new toilet seats and red toilet paper in the toilets. And hand-carved ice balls to calm her throat after the event.
