John Mayer has refused to comment on whether or not his latest single, 'Paper Doll', is about his ex girlfriend Taylor Swift.
There were rumours that it was a reply to Taylor's not so subtly named song, 'Dear John'.
But Mayer wasn't giving anything away, saying, "Songwriters write songs because of people, about people. I don't get involved in it. It's none of my business."
Some fans still think the song is about her, because of the lyrics "you're like 22 girls in one", which could be a reference to Taylor's song, '22'.
Have a listen to 'Paper Doll'...
