Rep: Charlie Sheen taken to hospital

Sheen, 45, was admitted to Cedars-Sinai Hospital in Los Angeles Thursday morning with what his rep described as "severe abdominal pains."

The actor told a source quoted by Extra: "I'm not dying." His friend, Steve Brodersen, told the TV newsmagazine Sheen's abdominal pain was the result of a hernia injury, made worse when Sheen laughed too hard at the TV.

Real Housewives of Beverly Hills stars Adrienne Maloof-Nassif and Dr. Paul Nassif, who are friends and neighbors of Sheen, told People they received a call from the actor's home Thursday morning.

"We did receive a call from Charlie's house this morning, asking for medical assistance and advice and immediately insisted the caller dial 911," the couple told the magazine in a statement. "Dr. Nassif also immediately called 911. ... As longtime friends, we are obviously very concerned about his well-being."

Another unnamed friend told People: "He doesn't think he's going to die. He doesn't want to stop. In his eyes, he thinks, 'I'm having fun, so what? I'm making $2 million a week, the show has the best ratings, I show up for up work. What's the problem?'"
