Emma Stone has revealed her beauty secret - confidence.
The 22-year-old actress - who has just been revealed as the new face of Revlon and plays Peter Parker's love interest in the much anticipated Spider-Man movie - told YouBeauty.com she's learned being herself is the key to looking good.
Emma said: "Confidence is the only key.
"I know a lot of people who aren't traditionally 'beautiful' - not symmetrical or perfect-bodied or perfect-skinned. But none of that matters because all that shines through is their confidence, humour and comfort with themselves.
"I can't think of any better representation of beauty than someone who is unafraid to be herself."
The Easy A star plays writer Skeeter Phelan in The Help, an adaptation of Kathryn Stockett's hit novel about race relations and servants in 1960s Mississippi, which has opened at number one in the US box office.
Emma said the role had taught her about inner beauty.
She explained: "I think at the beginning, understandably, she is deeply affected by her appearance and her mother's disapproval of it.
"Skeeter was lucky enough to have [her maid] Constantine, who reminded her that she was beautiful and smart and could choose her life."
