The Two And A Half Men star – America’s highest paid television actor – admitted himself voluntarily to the undisclosed facility.
The decision comes less than 48 hours after Sheen was rushed to hospital suffering from ‘severe abdominal pains’.
Although sources close to Sheen have denied the reports, several sources, including porn stars who claimed to be at his home that night, have said that Sheen went on a 36-hour cocaine bender that resulted in the early morning hospital dash.
'Charlie Sheen has voluntarily entered an undisclosed rehabilitation center today,' his publicist said.
'He is most grateful to all who have expressed their concern.'
Sheen’s hit comedy show has been placed on indefinite 'hiatus' while he undergoes treatment.
