Taylor Swift says her latest hit, 'White Horse,' is a like a fairytale without the happy ending.

"In the song 'White Horse,' you put everything you have into love and you get your heart broken," Swift tells The Boot. "More people have been able to relate to those songs -- the ones that I wrote when I was really going through something terrible."

Swift's new song is about a guy who breaks her heart and then tries to win her back. We're not sure who the real-life subject of the story is, but the man who will portray him in the video is Stephen Colletti, a guy who's broken his own share of hearts on reality TV.

Swift and Colletti were spotted filming scenes for the video in Nashville's Germantown neighborhood earlier this week. Colletti is best known for the MTV reality show, 'Laguna Beach,' where he romanced fellow stars Lauren Conrad and Kristin Cavallari. He has now moved into acting, with a recurring role on the TV drama, 'One Tree Hill.'

There's no word yet on when the 'White Horse' video will be released. In the meantime, watch her sing it live at AOL Music Sessions.
