Natasha Bedingfield will appear on-screen in the new Rocky film.

The singer had already been signed up to perform the theme tune for the movie, but now Sylvester Stallone wants her to take an acting role as well.

Bedingfield said: "Let's just say I'm excited and looking forward to seeing the script. It may be that I just perform the song at the end of the film."

The movie is expected to be released in December.
