CBS television said that production on "Two and A Half Men" -- the highest rated TV comedy in the United States -- was being put on hold as a result, and that it supported Sheen's decision.

"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.

Sheen, 45, the highest paid actor on U.S television, was rushed to Cedars-Sinai hospital with severe abdominal pains on Thursday. He left the hospital late on Thursday and was earlier said to be planning to return to the set of the TV show as scheduled next Tuesday.

"Due to Charlie Sheen's decision to enter a rehabilitation center, CBS, Warner Bros. Television and executive producer Chuck Lorre are placing 'Two and a Half Men' on production hiatus," CBS said in a statement.

"We are profoundly concerned for his health and well-being, and support his decision," the statement added. 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.
