Taylor Swift will never grow tired of writing about love.

The 22-year-old singer - who has dated stars including Taylor Lautner, Jake Gyllenhaal and Joe Jonas - will always be inspired by her relationships and is fascinated by how they change.

She said: "I think that love is always going to be a huge theme in what I write about just because there are no two similar relationships, there are no two times that you feel love the same way or hurt the same way or [feel] rejection in the same way. It's all different and I'm fascinated by that.

"I really love to go back to human interaction and the way we make each other feel. But that at 22 is different than it was at 18 or 19 when I made my last album and 16 and 17 when I made 'Fearless'. As you grow, you change in the way you process emotion."

Taylor is currently working on the follow up to her 2010 album 'Speak Now' and though her record label bosses are pleased with what she has done so far, she can't help but keep pushing herself further.

She told MTV News: "So far, I've been writing so much in the last year and the label keeps telling me, 'All right, we're finished; all right, we're satisfied; OK, this is done now.' And then I just keep writing and I keep turning it in in different versions

"I'm going to work on it until I literally have zero time left to work on it, because I'm having so much fun working on this album."
