Taylor Swift walks the red carpet at the 2010 American Music Awards, which are held on Sunday (November 21) at the Nokia Theatre L.A. Live in Los Angeles.

The 20-year-old country cutie was nominated for one award during the evening, and she won! Taylor received the award for Favorite Female Artist (Country).

Taylor thanked her fans, saying she had been given another reason to be thankful this Thanksgiving.

Taylor Swift debuted a sleek new look during her Sunday night performance at the American Music Awards.

The young pop/country crossover star was seen sitting behind a piano without her signature curls, instead sporting bangs and straight hair pulled back in a ponytail.

Swift, who won the American Music Award for Best Country Female Artist, performed her hit “Back to December,” which is thought to be an apology to former flame Taylor Lautner, before switching to OneRepublic’s “Apologize.”
