Emma Watson has rubbished rumours that she is set to star in the Fifty Shades Of Grey movie.

Last week it was reported that the former Harry Potter star had landed the role of Anastasia Steele, a student who enters a steamy relationship with a billionaire, in the upcoming film adaptation of the record-setting books.

But Emma has now taken to Twitter to set the record straight.

"Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life," she wrote.

The 22-year-old added: "Good. Well that's that sorted then."

Emma's name has been linked to the part for some time, and a host of top actors have been mentioned as contenders for the role of wealthy Christian Grey, including Ryan Gosling and Ian Somerhalder.

However, so far there is no official word on casting for the movie.
