They Did What? 9 Celebrities Who Lost it in Public

6. Mel Gibson

While this actor may have played some charming characters in his movies, I wouldn’t want to get on his bad side. In 2010, his child custody battle with Oksana Grigorieva took cussing and profanity to a whole other level. The phone conversations, which were taped and leaked to the press, recorded Mel threatening to burn Oksana’s house down and murder her. Needless to say, the actor lost a lot of credibility and respect, especially from his female fans.
