But all you are is mean/And a liar, and pathetic, and alone in life/And mean," Taylor sang on stage.

They may be harsh words for such a cute girl, but Taylor changed her tune when she went back on stage to accept her award for Entertainer of the Year.

"This is the first time that I've ever won this and I'm just losing my mind," she said. "The fact that this is from the fans makes it so beautiful. We just got back from Asia and Europe on tour. Thank you for this wonderful welcome home gift, and thanks for not forgetting about me. You are the best thing that has ever happened to me ever."
