For all the Taylor Swift fans out there (and there are a lot of them), here's good news: The songstress will allegedly be unveiling a brand new song, 'Sweeter Than Fiction,' next week. 

The song isn't for Swift's next studio album -- although she has hinted at what to expect from her upcoming release -- but should ease the wait until it drops.

'Sweeter Than Fiction,' which has been described as "poppy," is actually for a movie called 'One Chance.' The film follows the star of 'Britain's Got Talent' Paul Potts and his inspirational journey from being a Welsh steel mill worker to famed opera singer. One Chance' stars Julie Walters and James Corden and has drawn comparisons to 'The Full Monty' and 'Billy Elliot.'

"This is not a bullsh-- fairy tale," says film producer Harvey Weinstein (quote via ONTD). "It's gritty, a great cast, it's grounded."

The song will be added to the movie's soundtrack, and with the addition of the 'Everything Has Changed' singer, it will most likely garner quite a bit of attention. Swift wasn't alone in writing the mysterious new track, as she penned it with fun. guitarist Jack Antonoff.

Weinstein has credited Simon Cowell for getting Swift involved in the soundtrack, telling Daily Mail, "Simon knows her through the One Direction connection and he thought she'd be touched by the film, and he was right because she was." Anyone who knows Swift's songs is aware that she writes based on her emotions, so this seems like the perfect setup for her -- and for the movie.

The song, which reportedly plays during the closing credits of the film, will be unveiled at the movie's premiere at the Toronto International Film Festival next Friday (Sept. 6). Swift is no stranger to having songs on movie soundtracks, having previously written for 'Hannah Montana: The Movie,' 'Valentine's Day' and 'The Hunger Games.'
