Even the stars lose their cool sometimes!
Charlie Sheen's 2011 meltdown might have been the most memorable. Not only did the former Two and a Half Men star admit to substance abuse and blast the show's creator Chuck Lorre in a series of interviews, he also coined the phrases "winning," "Tiger blood" and "Adonis DNA."
In March, the actor's antics proved to be too much and he was fired from the hit CBS show. (Ashton Kutcher went on to replace him.)
But Sheen wasn't the only star to freak out in the past year. Whitney Houston, Gerard Depardieu and Alec Baldwin all had airplane meltdowns, while Real Housewives stars Teresa Giudice and Taylor Armstrong lost their cool in front of reality TV cameras.
