Swift, 24, who dated the likes of John Mayer, Jake Gyllenhaal and Harry Styles, said developing her music year-on-year helps her 'nurture' their relationship, reported Femalefirst.
"People always talk to you about marriages and relationships, and they say relationships take work, and you have to keep surprising each other.
"And that I think the most profound relationship I've ever had has been with my fans. That relationship takes work, and you have to continue to think of new ways to delight and surprise them," she said.
