Taylor Swift and Zayn Malik have dropped a surprise duet single from the "Fifty Shades Darker" soundtrack.
Swift and the former One Direction singer both shared clips of "I Don't Wanna Live Forever" on Twitter late Thursday. The full song was made available on iTunes on Friday.
"I Don't Wanna Live Forever" was written by Swift, Sam Dew and Fun's Jack Antonoff. Antonoff also produced the track.
Antonoff co-wrote three songs with Swift for her smash album "1989," including "Out of the Woods."
Swift has not released new music since the fall of 2014, but has remained on the scene in 2016 in music-related drama. She had a feud with Kanye West and Kim Kardashian over the lyrics in West's song "Famous," and sparked controversy when she confirmed that she wrote ex-boyfriend Calvin Harris's hit "This Is What You Came For." And Zayn Malik, her duet partner for the new "Fifty Shades Darker" track, was a former One Direction band member alongside Swift's ex-boyfriend Harry Styles.
Since 2006, Swift has released a new album every two years, but this year a new single will have to suffice.
