Taylor Swift and Zayn Malik Tease New Duet Single From 'Fifty Shades Darker'

The song appears on the film soundtrack.

Swift, 26, released a video snippet of "I Don’t Wanna Live Forever" just before midnight Thursday on her social media accounts, set to scenes from the film.

She sings, “I gave you something, but you gave me nothing. What is happening to me?”

Then Malik, 23, takes over, singing: “I don’t wanna live forever, ‘cause I know I’ll be living in pain.”

Malik teased a different part on the song on social media, showing off his part of the duet.

It’s unknown who wrote the song: Swift, Malik, both of them or someone else entirely. Still, the song “I Don’t Wanna Live Forever” is available now on iTunes.
