Josh Hartnett In New York City With Girlfriend Sophia Lie (PHOTOS)

Josh Hartnett, you are one sneaky fellow.

The "Black Hawk Down" actor was spotted walking undercover in New York City this week with girlfriend, Norwegian model Sophia Lie.

Come on, Josh, step out more! We'd like some more of you in our lives.
