After crossing into the pop world with her record-breaking album 1989, Taylor Swift got back to her country roots Wednesday when she made a surprise appearance at the CMA Awards. Wearing a sparkly, slinky dress, the singer, 26, presented the entertainer of the year award. Swift said. "And I learned so much about what it means to be an entertainer from the remarkable artists in this arena tonight. That's just one of the reasons I feel so honored to present this next award to any one of these five outstanding nominees for Entertainer of the Year, and be a part of this historic night we'll all remember."
