A representative for Charlie Sheen confirmed that the troubled actor voluntarily entered an undisclosed rehabilitation center on Friday.

“He is most grateful to all who have expressed their concern,” Sheen’s rep, Stan Rosenfeld, told FOX411’s Pop Tarts in a statement. “Mr. Sheen asks that his privacy be respected at this time and that no additional informational will be provided.”

The “Two-And-A-Half-Men” star was rushed to hospital on Thursday morning with “severe stomach pains” after an alleged 36-hour party bender with porn stars and “a briefcase full of cocaine.” He was released Friday morning.

Consequently, filming for the hit CBS sitcom was on hiatus this week and was slated to resume on Tuesday, but production has now been halted indefinitely.

“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,” CBS Entertainment, Warner Bros. Television and Executive Producer Chuck Lorre said in a joint statement.

Sheen was also hospitalized last October after police were called to his trashed New York City hotel room, reportedly following another night of heavy partying.
