With reality TV shows for nearly every taste and topic, reality stars have become more famous than celebrities from sitcom shows and movies -- though not always for good reasons.

While some stars of reality shows and competition series programs find a way to endear themselves to their viewers and make them root for them at all times, several others over the years have managed to polarize not only their fellow cast members and their viewers, but occasionally even annoy the crews and producers of their shows as well.

On competition shows, the worst appears to come out in some of the contestants as they fight to win an overall prize, be it love, money, or some major business opportunity. In their efforts to win the ultimate prize, some of these competitors unveil less than lovable pieces of their personalities, making them the villains of their season once they rub fans the wrong way with their behavior.

The terrible personality traits are also revealed on other kinds of reality shows as well however, and aren't solely limited to competition shows. With cameras on nearly 24 hours a day, some reality celebs are unable to hide their true colors, and as a result, the traits that make them hated by fans have eventually revealed themselves.
