Josh Hartnett struggled to cope following his "really painful" split from Scarlett Johansson. The pair dated for a year after meeting on the set of movie BLACK DAHLIA, but went their separate ways in November (06) because their busy schedules made it impossible for them to spend time together. Hartnett says, "It was difficult spending so much time apart with all our different commitments and both of us flying all over the world. "At the end of the day we're just ordinary people and it didn't work."
