Celebrity website TMZ.com was the first to report Sheen's hospitalization Thursday. TMZ says Sheen was taken by ambulance following an early morning 911 call.
The Emmy-nominated star of CBS' "Two and a Half Men" has been dogged by personal problems and apparent health issues. This is his third hospitalization in as many months. And just last week, CBS entertainment president Nina Tassler said network officials "have a high level of concern" about his off-camera behavior.
