2) The “Anger Management” Star: Charlie Sheen
He made “Tiger Blood” and “Winning” instant catch phrases and had the world watching his Twitter account for the next installment of his crazy rants. While never the tame sort, the actor and former star of “Two and a Half Men” seemed to go off the deep end in 2011. In January of that year, he was hospitalized for severe stomach pains and then upon his release, entered rehab. And in February he began a public feud with Chuck Lorre, the creator of “Two and a Half Men,” which resulted in Sheen getting his walking papers.
Of course, the firing just inflamed Sheen, who went on a Tweeting binge, blasting out one bizarre message after another to his fans. Some fans and critics thought that Sheen was just acting crazy; while others believed he could actually be bipolar. Whatever was going on, Sheen’s behavior seemed to gradually improve. That is — until the beginning of 2014, when the actor seemed to return to his 2011 form. In February 2014, the actor raged via Twitter that he would put Ashton Kutcher — his “Two and a Half Men” replacement — in the hospital. He also ranted against Rihanna. Could another Sheen meltdown be in the making?
