csheen127a.jpg After being rushed to the emergency room yesterday morning, actor Charlie Sheen has now checked into rehab.

His rep tells X17online, "Charlie Sheen has voluntarily entered an undisclosed rehabilitation center today. He is most grateful to all who have expressed their concern. Mr. Sheen asks that his privacy be respected at this time and that no additional informational will be provided."

Sheen was admitted to Cedars-Sinai Medical Center around 7am on Thursday after complaining of severe abdominal pain, and was released later in the evening.

Sheen's rep stated that he suffered a hernia, but various online reports speculated that the sit com star was admitted to the hospital after an alleged two day alcohol binge with several women at his Los Angeles home.

Though it was previously reported that Sheen would return to work next week, Two And A Half Men will go on hiatus until further notice. A rep for CBS has issued the following statement:

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