Malik’s Twitter post was accompanied by a stylised image of a masquerade mask over an inky background, while Swift’s Instagram post featured footage from the film, in which Dakota Johnson and Jamie Dornan reprise their roles as Anastasia Steele and Christan Grey.
The former One Direction singer also posted a picture of himself with Swift and a cat on his Instagram profile, which was liked more than 300,000 times within an hour.
The film has the unlikely release date of February 14, 2017 — Valentine’s Day.
The R’n’B track is currently available only through Apple Music.
Swift dated Malik’s former bandmate, Harry Styles, in 2013.
