Vamping it up: Emma Stone turns up the heat at the premiere Of Gangster Squad

Emma Stone arrived looking every inch the sensational leading lady in a scarlet strapless dress for the Gangster Squad premiere.

Stone, who plays gangster's moll Grace Faraday, showed her femme fatale credentials, holding her own against the cast of gangsters in Hollywood last night.

Her male co-stars gave 24-year-old Emma a run for her money, looking highly polished in their sharp suits. The trend was for a three-piece, but Russell Brand went for a more rock and roll look, with a skull print scarf and sunglasses accompanying his dinner jacket.

Ryan Gosling was the undisputed heartthrob. He may be dating actress Eva Mendes, but he still has time for his mother - she was his close companion for the evening.
