Scarlett Johansson debuted long locks on the set of Don Jon's Addiction in New Jersey yesterday. She was joined for the afternoon of filming by costar Joseph Gordon-Levitt, who is also the writer and director of the comedy. Scarlett's been busy with back-to-back projects lately, including wrapping work on Hitchcock and the successful May release of The Avengers. When she wasn't hard at work, Scarlett spent downtime with her latest flame, Nate Naylor. The duo vacationed together in February, though recent rumors suggest they may have broken up.
