Denis Leary, Zooey Deschanel and Sarah Silverman are criticizing the troubled actor via Twitter.

Since Charlie Sheen's most recent outbursts last week that led to the cancellation of the remaining season of CBS' Two and a Half Men, fans have blasted the actor via Twitter.

Seems most of Hollywood isn't standing by him, either.
Sarah Silverman Tweeted: "If I hung out w 20 year old porn stars all the time time I'd think I was a genius too."
Denis Leary wrote, "Is it just me or is Charlie Sheen starting to sound a lot like Moammar Kaddafi?"
Cracked actress Zooey Deschanel: "MYSTERY SOLVED: now we know who the "half a man" is in "two and a half men."...HINT: it's not the kid!!!!"
Who is standing by the troubled actor? CNN's Piers Morgan.
"Is it just me that thinks Charlie Sheen be allowed to behave how the hell he likes in his own time?" he Tweeted.
