Taylor Swift has gotten plenty of songwriting material out of her past relationships, but now the tables have turned as One Direction's new song is reportedly about her.

More specifically, it seems to be inspired by the fling that she had with Harry Styles - the same brief relationship that allegedly informed songs from her own album '1989', including 'Style' and 'Out of the Woods'.

It's called 'Perfect' and premiered this morning, with lyrics like "And if you like cameras flashing every time we go out /  And if you’re looking for someone to write your breakup songs about / Baby, I’m perfect / Baby, we’re perfect". Mmm-hmmm.
