Troubled actor Charlie Sheen was rushed to the hospital this morning, according to TMZ. A source at the hospital told TMZ that “it’s serious.”

TMZ said that the 45-year-old Sheen was taken out of his house on a stretcher and loaded into an ambulance at 7 a.m. (Pacific time) after a 911 call was placed at 6:35 a.m. He was subsequently transported to Cedars-Sinai Hospital in Los Angeles.

“Two young women exited the house at the same time Charlie was taken out with a towel partially over his face,” TMZ stated.

Sources told TMZ Sheen was suffering severe abdominal pains which triggered the 911 call. Sheen’s father, Martin Sheen, and his mom, Janet Templeton, are now at the hospital.
