“Two and a Half Men” star Charlie Sheen was taken to Cedars-Sinai Medical Center on Thursday, reportedly after experiencing severe abdominal pains.Sheen has been in the headlines in recent weeks with reports about his hard-partying lifestyle. Those reports have raised questions about his ability to continue as the star of the hit CBS laffer, though so far there has not been any disruption of production on the Warner Bros. TV show. “Men” is on a previously skedded production hiatus this week. It was unclear whether Sheen remained in the hospital by midday Thursday. Reps for Sheen and Warner Bros. TV declined comment.
