And, in a statement to Access Hollywood, his rep said doctors had yet to diagnose the star.

" Josh Hartnett was released from the hospital earlier this week after being admitted to Cedars-Sinai with gastrointestinal discomfort," his rep said in a statement to Access. "He has undergone a battery of tests to determine the cause and in the meantime he is resting and feeling fine and thanks everyone for their concern."
