Most famous people work hard to give off an otherworldly vibe while they're in the public eye. That seems obvious, considering that most regular people see celebrities as aliens. Let's not forget that before their fame, movie, and music stars were simply individuals, and some of them were allegedly really terrible people. It's easy to assume you know which celebs are the most abrasive at times.
For fear of the fan spilling the beans to the press, most nasty celebrities strive to keep their disrespectful conduct under wraps. In contrast, pre-fame celebrities with bad manners let their rudeness fly without fear of repercussions from the press or the scrutiny of internet commenters. Many famous people have publicists who can put a positive perspective on their purportedly rude actions, but other stars really are jerks at heart, and this list will show who they are.
