Jennifer Lawrence covered up in a floor-length fur coat and glamorous updo to join costar Bradley Cooper on the Boston set of their untitled David O. Russell project today. Bradley was sporting tightly curled locks for the day of filming. Today marks the first time we've seen Jennifer and Bradley, who starred together in Silver Linings Playbook last year, hit the New England set together; however, both have popped up for work on the film separately. Jennifer wore the same updo for the cameras last week, while Bradley also appeared with pink curlers in his hair last month.
