LOS ANGELES, Calif. -- Actor Josh Hartnett was rushed to the emergency room early Monday morning, Access Hollywood has confirmed.

" Josh Hartnett walked into an ambulance at approximately 1:45 AM this morning 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,'" Hartnett's rep said in a statement released to Access.

After arriving, an ambulance transported the person to an LA area hospital, a rep for LA City Fire told Access.

A RadarOnline source claimed that Hartnett "looked pale, dirty and disheveled" and that he "stumbled around the hotel bar" on Friday night. The source added, "he didn't appear to be drinking, but he wasn't himself. He looked troubled. He didn't seem to have anyone with him."

According to Variety, production on Harnett's latest movie, "Queen Of The South," co-starring Eva Mendes and Ben Kingsley, was halted last week when director Jonathan Jakubowicz claimed that a Mexican drug cartel threatened him for making the film.
