Charlie Sheen was rushed to Cedar Sinai Hospital in Los Angeles early Thursday morning.
Stan Rosenfield, Sheen's publicist, told ABCNews that the actor "was having severe abdominal pains and went to the hospital." There was no immediate information on his condition.
TMZ.com reported that Sheen was taken out of his home on a stretcher and loaded into an ambulance at 7 a.m.
It is more bad news for the "Two and a Half Men Star," who has had to face questions about his career after what police described as an alcohol-fueled rampage at New York's famed Plaza Hotel last fall and highlypublicized marital problems with actress Denise Richards.
CBS Entertainment President Nina Tassler told TV critics in Los Angeles earlier this month that there is "a high level of concern. How could we not? This man is a father. He's got children. He has a family. So obviously, there's concern on a personal level. But you can't look at it simplistically. Charlie is professional. He comes to work. He does his job extremely well. It's very complicated."
"It's always a little weird because like the stuff you hear is just unbelievable," said "Men" co-star Jon Cryer to Conan O'Brien Wednesday. "I mean like ... I'm checking TMZ, as I do every day, to know if I have to go to work at all."
TMZ was the first to report that a 911 call was placed from Sheen's home at 6:35 a.m. this morning. The gossip website reported later today that Sheen was having a "wild" party with five women before being taken to the hospital.
Sheen's ex-wife, Denise Richards, arrived at Cedars-Sinai Medical Center in the afternoon, according to Us Magazine.
"Thank you so much for you kind and supportive messages..it means a lot ...thank u...xo," the actress tweeted.
