LOS ANGELES (Reuters) - Actor Charlie Sheen, star of the most-watched comedy on U.S. television, was rushed to a Los Angeles hospital with severe abdominal pains on Thursday, his spokesman said.
"All I know is, he was having severe abdominal pains and went to the hospital," Sheen's spokesman Stan Rosenfield said in a statement.
Rosenfield told Reuters that he had gone to the hospital to see the star of "Two and a Half Men" but was told the actor was sleeping. He added that Sheen's father, actor Martin Sheen, and his mother Janet Templeton, were on their way to the hospital.
Celebrity website TMZ.com said the actor's second wife Denise Richards was also at the hospital, where unspecified tests were being carried out on the actor.
It was the latest in a string of incidents in Sheen's personal life -- his assault conviction last year, stint in rehab, and recent reports of hard drinking, partying, and drug use -- that have caused concern for executives at broadcaster CBS, which airs "Two and a Half Men".
Sheen, 45, is the highest paid TV actor in Hollywood, and "Two and a Half Men" is No. 1 comedy on U.S. TV, raking in revenue for CBS and the show's makers at the Warner Bros. film and TV studio, a unit of Time Warner Inc.
TMZ.com said Sheen was taken from his Los Angeles area home on a stretcher and rushed by ambulance to the hospital after a 911 emergency call was placed.
The website said the call followed a noisy party at Sheen's house on Wednesday night. Two women left the house as Sheen was taken out at 7 am on Thursday morning, TMZ said.
Earlier this month, executives at CBS said they were highly concerned about Sheen, but added that at work he behaved in a professional manner and that "Two and A Half Men" would continue. Sheen plays a womanizing bachelor on the comedy.
Sheen was convicted last year for a December 2009 attack on his, then third wife in Aspen, Colorado, and he was ordered to drug and alcohol rehab.
In October, he was briefly hospitalized in New York when police found him acting drunk and incoherent in his room in the company of a porn star. His spokesman said at the time he had a bad allergic reaction to medication. Media reports said he had trashed his hotel room.
Two week ago, TMZ.com and other celebrity media outlets reported Sheen was at it again, partying hard in Las Vegas with porn stars and coming close to being late for rehearsals in Los Angeles for his TV show.
Sheen has five children from three marriages and he signed up in May 2010 for two more seasons of "Two and Half Men." No filming is scheduled this week for the show.
