LOS ANGELES Jan 28 (Reuters) - "Two and A Half Men" actor Charlie Sheen has entered rehab, his publicist said on Friday, a day after being hospitalized following reports of a 36-hour drug and drink-fueled party at his home.

"Charlie Sheen has voluntarily entered an undisclosed rehabilitation center today. He is most grateful to all who have expressed their concern," the actor's spokesman Stan Rosenfield told Reuters.

Rosenfield said that Sheen had asked for his privacy to be respected and that no additional informational will be provided.

CBS said in a statement that production on "Two and A Half Men" was being put on hold and that it supported Sheen's decision.

Sheen, 45, the highest paid actor on U.S television, was rushed to a Los Angeles hospital with severe abdominal pains on Thursday.

Sheen reportedly earns about $27.5 million a year for his starring role as a womanizing bachelor on "Two and A Half Men," the No. 1 comedy on U.S. television with some 15 million weekly viewers.

But his personal issues, including stints in rehab, an admitted penchant for porn stars and prostitutes, and a 2009 attack on his wife, have dominated headlines for the past year and caused concern among network executives at CBS, which broadcasts the show. (Reporting by Jill Serjeant: Editing by )
