Josh Hartnett was solo Thursday for a walk in NYC. Earlier in the week, his girlfriend Sophia Lie was by his side for a romantic couples lunch. The actor has been getting ready for Summer in the Big Apple over the last few weeks by relaxing and hanging out with friends. He's resting up for a return to the big screen with Gunslinger, while his movie Demi Moore and Woody Harrelson is scheduled to arrive in theaters later this year.
