Screen siren Monica Bellucci embraces nudity in movies because she believes the naked human body is a perfect tool of expression.

The 36-year-old actress is proud of her femininity and is baffled by stars who refuse to disrobe.

She says, "I'm not scared by nudity, because for me, nothing is more beautiful than a body. You can have such amazing emotion from a body.

"In IRREVERSIBLE, I treated my body like it was an object and it's great when you can have this kind of relation with your body, it's a part of your job, an object you can work with.

"When you can have this kind of freedom it's the moment where you can give your best as an actress."
