Charlie Sheen wasted no time on Friday to mock the decision to replace him on 'Two and a Half Men' with Ashton Kutcher, calling the 'That '70s Show' alum a "sweetheart" but a choice that would bring the show down. Despite his public show of gravitas, a source close to Charlie tells me that privately he's "destroyed" by the casting news.

"He really thought that he would be invited back," a friend of Charlie's tells me. "After years of suffering no consequences for his behavior, why would he think anything else? Finally it has sunk in that he doesn't live by different rules to everyone else. Actions do have a consequences."
