Taylor Swift, by far, had the most fun of anyone at last night's Grammys! It's fun to see her enjoying herself when so many music artists take themselves so seriously. See Taylor dancing like a dork, head-banging at the piano, and hanging with some of the pop stars.Here is Taylor's evening last night at the Grammys.
