'Harry Potter' fame actress Emma Watson says she is 'terrified' about singing for the first time onscreen in her upcoming film 'Beauty and the Beast', reports IANS.

The 24-year-old, who will play the role of Belle in the film -- which will star Dan Stevens as The Beast and Luke Evans as Gaston -- told Total Film magazine that singing was an unexpected challenge for her, reports eonline.com.

‘I sing, so that's really unexpected. I've never had to do that for a film before, and I think people will be interested to see me do something very different like that,’ she said.

‘It gives me a different challenge, really. That's terrifying in and of itself,’ she added.
