An ambulance picked up Josh a 1.45am and rushed him to the Cedars-Sinai hospital in Los Angeles where he walked into the emergency room without any additional help.
His publicist Susan Patricola confirmed: "Josh Hartnett walked into an ambulance at approximately 1:45am suffering from 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.
