Charlie Sheen: Dancing Days Before Rehab?

Feb. 4, 2011 — -- 'Ho boy, Charlie Sheen's not looking good.

A newly released video of the "Two and a Half Men" star shows Sheen dancing wildly at a bar with three women, throwing his hands in the air and repeatedly yelling "ho!"

According to TMZ.com, which first obtained the video, the footage was shot last week, at the start of Sheen's purported drug-fueled partying spree with an adult film star. Sheen's publicist did not immediately return ABCNews.com's request for comment about the video.

Meanwhile, the actor continues to undergo rehab at his Los Angeles home. On Thursday, Sheen's publicist confirmed that the actor hopes to return to the set of his hit CBS comedy by the end of February. "Two and a Half Men" went on hiatus last week, after Sheen was hospitalized and entered rehab.

On Wednesday, Sheen put out a written statement -- his first public comment since his hospitalization. He thanked fans, co-stars and CBS for support during his time of trouble.

"I have a lot of work to do to be able to return the support I have received from so many people," he said. "Like Errol Flynn, who had to put down his sword on occasion, I just want to say, 'thank-you.'"

CBS executives have said that they were increasingly worried about the sitcom star, but that there was little they could do because Sheen showed up to work on time and fulfilled his contract.

In January, CBS Entertainment President Nina Tassler told TV critics in Los Angeles that there is "a high level of concern [around Sheen]. This man is a father. He's got children. He has a family. So obviously, there's concern on a personal level. But you can't look at it simplistically. Charlie is professional. He comes to work. He does his job extremely well. It's very complicated."

Addiction specialists aren't so easily convinced.

"Sure he goes to work, but that's not the same thing as having quality of life," said Kristina Wandzilak, founder of Full Circle Interventions. "And he also has a whole team of people around him that are getting him to work."

Getting celebrities sober can be very difficult because several people rely on that celebrity to support them financially, according to Wandzilak.

"You're not just intervening on an individual, but a small industry," she said. "Charlie Sheen is a small industry and he has many people working for him and many people that need him to show up for work. ... Because they're invested in him showing up, the truth is they're going to be unable to put his health first."

But Sheen has his supporters. On "The View," actress Whoopi Goldberg said she related to Sheen and that, for many years, she was a functioning addict.

"I went to work because I knew that if I didn't show up, a lot of people would be out of work, and I wouldn't get a check and would not have the lifestyle that I needed to buy my drugs," she said. "Until Charlie makes the decision that he's ready and willing to stop doing what he's doing because he can't do it anymore, he will do that. But he's not there yet."
