UPDATE:TMZ now reports that the initial reports were premature, and that Tom Petty is still alive. However, Petty has been pulled from life support and is not expected to live:
Sources tell us at 10:30 Monday morning a chaplain was called to Tom's hospital room. We're told the family has a do not resuscitate order on Tom. The singer is not expected to live throughout the day, but he's still clinging to life. A report that the LAPD confirmed the singer's death is inaccurate — the L.A. County Sheriff's Dept. handled the emergency.
