Although the pair collaborated on the track, 'I Don't Wanna Live Forever', which will feature on the 'Fifty Shades Darker' soundtrack, producer Jack Antonoff revealed that they didn't actually record the duet together.
He tweeted: ''i don't wanna live forever came together very quickly. wrote it with taylor and sam dew and produced it at home mostly on paper sounds
''recorded taylor at my house. zayn sent parts from LA - we did it in a week basically. i've never had something come out that quick
''loved making this song with taylor sam and zayn (sic).''
The 'Shake It Off' hitmaker - who previously dated Zayn's former One Direction band mate, Harry Styles - shared a clip of the song on Instagram.
In the preview, she sings: ''Baby, baby, I feel crazy/Up all night, all night and every day/Give me something, oh, but you say nothing/What is happening tonight?''
And the 'Like I Would' singer then belts out: ''I don't wanna live forever/'Cause I know I'll be living in pain.''
The track is already at the top of the US iTunes chart, knocking Machine Gun Kelly and Camila Cabello's 'Bad Things' off the top spot.
The single from the eagerly-anticipated sequel to 'Fifty Shades of Grey' is the 26-year-old pop beauty's first new music since 2014's '1989'.
It's Zayn's third collaboration this year, following 'Freedun' with M.I.A and 'Cruel' with Snakehips.
It follows Taylor's only full concert of 2016, after she performed last month at the Formula 1 United States Grand Prix.
