Josh Hartnett's out of Hospital After Tummy Trauma

The actor has left the hospital following his stomach problems early Monday morning

Josh Hartnett's tummy must be feeling better.

The Sin City stud was taken by ambulance to Cedars-Sinai Medical Center in Los Angeles early Monday morning for severe abdominal pain. He has since checked out.

"He is out of the hospital," Hartnett's rep, Susan Patricola, tells E! News. No further details—including the actual date of his release—were given.

However, Sienna Miller reportedly flew from Miami to visit him in the hospital Wednesday.

Earlier this week, Patricola described the stomach problems as "a flare-up of a gastro-intestinal problem that plagued him while he was starring in the west end of London during the production of Rain Man."
