Bradley Cooper was busy on the Philadelphia set of The Dark Fields yesterday with his costar Robert De Niro before grabbing a late coffee with friends. Production on the film had Bradley in NYC for a few weeks, but he's back in his home city of Philly for the time being. His girlfriend Renee Zellweger stayed behind in the Big Apple, where she put on a strapless Carolina Herrera to attend Monday's Costume Institute Gala. Bradley couldn't attend as her arm candy, but she was able to mingle with a crowd that included his A-Team costar Jessica Biel. Bradley, Jessica and the rest of the cast will all reunite in the coming weeks as they gear up for the June 11 release of their Summer blockbuster.
