Taylor Swift is lending her voice to her favorite TV show. 'White Horse,' a song from the country sensation's upcoming sophomore album, will be featured in the season premiere of 'Grey's Anatomy.'

"You should've seen tears streaming down my face when I got the phone call that they were going to use that song on 'Grey's,'" Swift tells Billboard. "I have never been that excited ...This is my life's goal -- to have a song on 'Grey's Anatomy.'"

'White Horse' will appear on Swift's 'Fearless' album, due in stores November 11. She says the song is a perfect fit for the medical drama.

"It talks about falling in love and the fairy tales that you are going to have with this person, and then there is that moment where you realize that it is not going to happen. That moment is the most earth shattering moment."

'Grey's Anatomy' airs this Thursday at 9 PM ET on ABC. Swift is one viewer sure to be glued to the two-hour season premiere.

"My love of 'Grey's Anatomy' has never wavered," she says. "It's my longest relationship to date!"
