LOS ANGELES - Demi Moore smoked something before she was rushed to the hospital on Monday night and was convulsing and "semi-conscious, barely," according to a caller on a frantic 911 recording released Friday by Los Angeles fire officials.

The woman tells emergency operators that Moore, 49, had been "having issues lately."

"Is she breathing normal?" the operator asks.

"No, not so normal. More kind of shaking, convulsing, burning up," the friend says as she hurries to Moore's side, on the edge of panic.

The recording captures the 10 minutes it took paramedics to arrive as friends gather around the collapsed star and try to comfort her as she trembles and shakes.
