Josh Hartnett 911 -- Abdominal Pains

Josh Hartnett was taken to Cedars-Sinai hospital early this morning, ending his night at the Chateau Marmont in West Hollywood.

The 911 call came in at 12:53 AM and the caller said abdominal pains were the issue.

The ambulance picked up Josh at about 2:00 AM. He walked on his own power -- no stretcher was needed.

UPDATE 12:57 PM We're told Josh was in "excruciating pain" last night, because of gastrointestinal issues. We're told he may have picked up some sort of stomach virus while shooting a movie overseas, and he's had ongoing stomach issues as a result. He's seeing a specialist today.
