Last year, 'True Blood' star Ryan Kwanten offhandedly said that he'd love to see Taylor Swift make a guest appearance on the HBO series. Now Kwanten -- who plays Jason Stackhouse -- is getting his wish … almost. Swift's music will make an appearance during Sunday's episode.

Rolling Stone reports that 'Haunted,' a track from Swift's 'Speak Now' album, will appear during what 'True Blood' music supervisor Gary Calamar calls "a racy, sexy scene." Calamar plays coy when Rolling Stone suggests it could be a scene between Jessica and Jason. "I'm going to leave it right there," he says.

Swift's team reportedly refused to let the song be part of the blood-thirsty fun at first, but the singer herself stepped in to make it happen.

The string-heavy song has lyrics that seem perfectly suited for a sexy vamp scene. "Come on, come on, don't leave me like this / I thought I had you figured out / Something's gone terribly wrong / You're all I wanted  / Come on, come on, don't leave me like this / I thought I had you figured out / Can't breathe whenever you're gone / Can't turn back now, I'm haunted."

Swift should be able to take in the episode from the confines of one of her own homes, as she'll be enjoying a break between tour stops in Canada and Los Angeles.
