On his rendition, the former One Direction-er reinvents the Lover title track as an electric guitar-fueled rock ballad. "We can leave the Christmas lights up till January/ 'Cause this is our house and we make the rules/ And there's a dazzling haze and mysterious way about you dear/ Have I known you twenty seconds or twenty years?" he croons before tossing the second verse to Capitol labelmate Fletcher.
For her part, Swift gave the cover her stamp of approval on social media following its release. "This is absolutely STUNNING," she wrote, sharing the track on her Instagram Story. "@niallhoran & @findingxfletcher LOVE YOU GUYS."
