Bradley Cooper attended the premiere of his new film called Burnt last night and thanked Gordon Ramsey for helping him prepare. Burnt follows Adam Jones – who is played by Cooper - as he tries to regain being a top chef in London after a career meltdown caused by drugs and alcohol. The actor, who stars alongside Sienna Miller in the new comedy-drama movie, said the notoriously foul-mouthed chef played an important role in his on-screen performance, which sees Bradley play an up-and-coming chef whose drug use causes him to lose his restaurant. He told The Sun newspaper: "Gordon was invaluable. He shared so much. He was amazing." Sienna Miller also appeared on the red carpet wearing a sparkling sequin dress from the Marc Jacobs Spring 2016 collection.
