Emma Watson has denied rumours that she will star in the Fifty Shades of Grey movie.

The Harry Potter star, who was pegged as the "frontrunner" for the role of Anastasia Steele in the film adaptation, told Entertainment Weekly that she has not even read the EL James bestselling book.

She explained: "I haven't read the book, I haven't read a script, nothing. There are so many movies you become attached to when I've literally never even received a phone call.

"It was the same way with The Girl With the Dragon Tattoo - I never even saw a script!"

Watson added that many of her friends asked her about the Fifty Shades rumours after they emerged last week.

She said: "I told them just because there are 60 articles on the internet doesn't mean it's any less true than if there are three or four."
