"The next thing I remember is using my fingers, the small fingers of a child, to dig the pills my mother had tried to swallow out of her mouth while my father held it open and told me what to do," she said.

"Something very deep inside me shifted then and my childhood was over."

The Ghost star went to rehab in the 1980s for drug and alcohol addiction treatment, and was according to People magazine was hospitalised in January 2012 after collapsing in her Los Angeles home.
