Celebs are no strangers to controversy, but a few completely lost their heads this year and found themselves in more trouble than they (or we) ever could have expected. We were absolutely shocked when Mel Gibson was pulled over for drunk driving and proceeded to verbally attack everyone around him with anti-Semitic and sexist remarks. Similarly Michael Richards went on a racist rant on two African American men at an LA nightclub. Both men have since apologized but the damage has been done. Their lovable images are tarnished and it's doubtful either of their careers will ever fully recover.
