The singer has released the clip for her new track 'A Thousand Years', which will feature in the forthcoming Breaking Dawn - Part 1 movie instalment.
The video features Perri holding a candle and singing the love ballad, while clips from Breaking Dawn are interspersed throughout.
Footage from the movie includes images of the wedding invitations being handed out, as well as a preview of the marriage ceremony itself.
Perri told The Hollywood Reporter that she was inspired to write the track after seeing an early screening of the film.
She explained: "I cried the whole time, then I went home and wrote the song about Edward and Bella and their love affair. It's probably the most romantic, lovey-dovey song I've ever written."
Initially 'A Thousand Years' was planned to be the second cut to be lifted from the Breaking Dawn soundtrack.
However, Bruno Mars's 'It Will Rain' has been delayed, as the singer revealed that he is still working on the final music video for it.
The Twilight: Breaking Dawn - Part 1 soundtrack will be released on November 7 in the UK and November 8 in the US.
The film's release will follow a few weeks later on November 18.
