We should have seen it coming: Taylor Swift and Zayn Malik have just dropped a sneaky collab.
I Don't Wanna Live Forever is the theme song for the latest film in the Fifty Shades of Grey series, Fifty Shades Darker.
The pair, who presumably became friends thanks to Malik's relationship with 'squad' member Gigi Hadid, both posted a snippet of the track on their respective Instagram accounts last night, and the song quickly shot to the top of the iTunes chart.
It was co-written by Swift, Sam Dew and Jack Antonoff, boyfriend of Girls writer and star Lena Dunham, who has worked with Swift on numerous previous tracks.
Fifty Shades Darker, starring Jamie Dornan and Dakota Johnson,hits cinemas in February.
