Duffy recording new track for movie

Rex Features

Duffy has agreed to record a theme for upcoming movie How To Lose Friends And Alienate People.

Producers of the film, which stars Simon Pegg, approached the Welsh singer following the success of her debut album Rockferry.

A source told The Sun: "It will be a romantic number. Producers think her involvement will be great for raising the film's profile."

The track will be released as a single in October to coincide with the movie's cinema debut.
