Cameron Diaz smiled yesterday while spending her morning working on The Green Hornet in LA. It's been a busy month for Cameron after her stint in Europe filming Knight and Day with Tom Cruise, though they wrapped production just in time for Christmas. Cameron was back with Seth Rogen to continue working on their action flick, decked out in the same dress she wore while with him in September. Their efforts won't be on the big screen until this time next year, but in the meantime check out the new trailer for her upcoming movie with Tom.
