4. Mel Gibson
Mel Gibson is one of the richest actors in the world, having produced and starred in some of the biggest films ever made. But his private life has shown that he does not know how to conduct himself outside of the film business. In 2009 and 2010, multiple recorded tapes from ex-girlfriend Oksana Grigorieva, surfaced on several websites, which see the actor threatening to hurt her, amongst other things. He insults her appearance, makes it known that she can’t hurt him because of who he is and that she needed to respect him. This particular incident had shown Mel in a completely different light and having, therefore, affected his reputation in more ways than one.
