Cameron Diaz was in her Gambit costume yesterday to film a scene at the London Airport with her costar Colin Firth. We had a first look at Cameron and Colin in Gambit just yesterday, and it appears the actress has to wear a variety of out-there costumes in their remake of the 1966 Michael Caine classic. Cameron's legs were once again on prominent display, just as they were while she filmed Bad Teacher last year. We know the actress logs long hours at the gym after seeing photos of Cameron and her boyfriend, Alex Rodriguez, working out together and even tossing around tires during an outdoor exercise session a few months ago. Alex is currently back in the US, focusing on his fitness and Yankees season, with a final game in Tampa Bay tonight before heading to Baltimore tomorrow. Cameron will head back to America herself in the coming weeks to tend to press duties for Bad Teacher, and production on her current movie will also have her in New Mexico over the Summer.
