Tomlinson has appeared to confirm the group's latest single was penned about 21-year-old Styles' split from Swift, reported People magazine.
"I think everybody draws from personal experiences, so of course to a degree I'm sure that (Styles' break-up with Swift) influenced some of it. Down to specifics to who that song is exactly about, that's fan's interpretation, I suppose," Tomlinson said.
Meanwhile, Styles has reportedly been busy penning tracks for his solo career after the band go on a hiatus early next year.
