Oh no! Our favorite Josh (sorry Duhamel) checked into Cedars Sinai Medical Center late last night, complaining of stomach pains. His publicist Susan Patricola confirmed the news and released the following statement to X17online:

    "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 [staying] in the west end of London during the production of “Rain Man.” He is under observation but is resting comfortably."

X17 photogs on the scene tell us that even though Josh walked onto the ambulance (that's him on the right side of the pic), he looked quite under the weather.

And who is that girl with him? She looks kinda Kirsten Dunst-y...did those two bring their Sundance romance to LA? Or is this a new ladyfriend? Either way, we hope this hottie gets better!
