Kristen Stewart on ‘Breaking Dawn’ wedding song: ‘I just became instantly emotional’

Kristen talks about the song that is played during the wedding scene in Twilight: Breaking Dawn Part One.

Dedicated Twilight fans might recognize the song that plays during the long-awaited wedding between Edward (Robert Pattinson) and Bella (Kristen Stewart) when they see Breaking Dawn this weekend (if they haven’t seen it already; the film made over $30 million in midnight screenings Thursday night). It’s a special ‘wedding version’ of the Iron & Wine song, ‘Flightless Bird, American Mouth’ that played during the prom scene in the first Twilight movie way back when in 2008.

“Before we even started shooting the first Twilight with [director] Catherine Hardwicke, I was rehearsing with Rob and we were sort of dancing around this room, trying to do this scene,” Stewart tells EW. “I put on Iron & Wine’s ‘Flightless Bird, American Mouth’ and I just became instantly emotional. Rob couldn’t handle it — it got weird! But I was like, ‘oooh, this is perfect.’”

Stewart says that they ended up playing the song for her on-set when they filmed the actual scene, and the rest is Twilight history. Listen for parts of the song to play during the long-awaited love scene too: “I think our composer played with it and you hear the melody throughout the film,” says Stewart.
