Charlie Sheen and Denise RichardsNow that Charlie Sheen is finally getting the help he needs by heading into rehab, it would be easy for his ex-wife Denise Richards to capitalize on what has become the biggest celebrity story of the week by giving a tell-all interview.

But Denise won't do it. Insiders close to the actress say she has been inundated with interview requests and has turned them all down.

"Her focus right now is on Charlie getting better and being there for her kids. He is their father and Denise wants him healthy so that he can be a part of their life," a source close to the Richards' camp tells PopEater.

We hear that Denise plans to stay strong and support Charlie while he goes through rehab. A rep for the 45-year-old actor wouldn't confirm how long his client plans to be in treatment, but insiders say they expect him to be in for at least three months.
