Wow was she great, and so young! I liked her performance much better than Carrie's. She has the star appeal in her, yet she seems genuine and not so Hollywood at the same time. I thought she was very entertaining and was really having fun and getting into it. She also seemed very humble, happy, and a little overwhelmed/stoked/flattered about performing for such a big crowd. I wasn't expecting much (everyone I had heard said she was just for teeny boppers) but I was very impressed.
