Was Rehab Charlie Sheen's Choice?

Charlie Sheen's representatives released a statement Tuesday that the actor had entered rehab as a preventative measure—but was it his choice to go? INSIDE EDITION has the latest.

INSIDE EDITION is learning that Charlie Sheen's ex-wife, Denise Richards, contacted an executive from Two and a Half Men the day before, reportedly saying she was concerned about him relapsing, and wanted someone to convince him to go to rehab.

Mystery is swirling around Sheen's decision to enter rehab. Sheen's representatives announced early Tuesday afternoon the actor had checked into rehab. But it wasn't until seven hours later, at 8 p.m. PST, when he reportedly checked in. So why the delay? At his Beverly Hills home he was reportedly dragging his feet about going, and his team tried to force his hand by releasing the statement.

"Charlie didn't want to go," a source told radaronline.com. Psychiatrist Dr. Charles Sophy, the author of the self-help book Side By Side, says people often try to back out of going to rehab at the last minute.

"You get to that door, denial kicks in. 'Oh I can do this. It's not as bad as I thought it was. I can handle it as an outpatient. I don't need to go in there.' That's the time you've got to push through that, get in that front door and connect yourself to treatment," said Dr. Sophy.

Sheen reportedly checked into a facility because he was abusing alcohol and cocaine. It's his third stint in rehab, according to published reports. His official statement called the move "a preventative measure."

"If you feel the need to go inpatient, and inside, and away from the distractions of life, then you probably are using," said Dr. Sophy.

With Sheen's wife Brooke Mueller also in rehab, the couple's twin boys are in the care of family members and a nanny who used to work for actress and TV personality Lisa Rinna. Rinna tweeted "Good news is the Sheen babies are being well taken care of by our beloved nanny that was with us for 6 years. She is a godsend."

CBS and the producers of Two and a Half Men are expressing their support for Sheen, releasing this statement: "We wish him nothing but the best as he deals with this personal matter. Production on Two and a Half Men will be temporarily suspended."

Hollywood is also rallying around TV's highest-paid actor. INSIDE EDITION spoke to Stephen Baldwin, who's battled his own addiction problems.

"Learning and becoming knowledgeable of how to help yourself deal with it, no matter who you are in the equation, is always good," said Baldwin.
