Well this is unexpected.
Taylor Swift has come out of nowhere to drop a new song with Zayn Malik for Fifty Shades Darker.
I Don't Wanna Live Forever is a dark, R&B-centred tune that is very much out of Swift's comfort zone and very much in Zayn's comfort zone.
It gives a lot of merit to the rumours that Swift was working on an R&B record as the follow-up to 1989, potentially featuring Drake.
We're still waiting for it to hit Apple Music in Australia (arghhhhh) but listen to a preview below.
