Lower East Side bar regular Josh Hartnett proved himself to be a stand-up citizen the other night. Hartnett and his pals closed down Essex Street watering hole Whiskey Ward, and as they were leaving at 4 a.m., "he stopped a guy from harassing a woman," said our source. "He was just helping her out." No punches were thrown - there were just some raised voices on the corner. A rep for Hartnett - who went to war in "Black Hawk Down" and solved a damsel's murder in "Black Dahlia" - had no comment.
