LOS ANGELES (AP) - Don't be surprised if Taylor Swift writes a song about Ozzy Osbourne. No, they aren't dating or anything - but he did tell a joke at her expense backstage at the Grammys. When he came back to speak with reporters, he was asked about his comment that he was a fan of Taylor Swift. Ozzy said he certainly was - then deadpanned: Who the (expletive) is Taylor Swift. Of course, Ozzy being Ozzie there weren't many people who even understood what he was saying, so maybe she won't be upset.
