Katy Perry debuted a new song at the Grammys tonight, and she may have also debuted a little message for her ex, Russell Brand. The song, "Part of Me," includes the lyrics, "Now look at me, I'm sparking/A firework, a dancing flame/You won't ever put me out again" and "So you can keep the diamond ring." People, and at least one of the magazine's readers, think the lyric just might be a shot at Brand. Click for more Grammys coverage.
