You wrote a song on your new CD with Taylor Swift. What's one thing about her that fans don't know?

Nothing! She's an open book. Everybody knows she's just a sweet girl who loves her fans. She called me the other night and said, 'All these kids are outside screaming. I'll feel horrible if I don't go out and sign stuff!' She goes out of her way, and she's a great friend. I don't know anything that other people don't know ... oh, other than she's actually a man. [laughs] Her hair isn't real. No, I'm kidding.
