Taylor Swift is once again the belle of the awards ball. Less than two weeks after winning Entertainer of the Year, the top honor at the CMA Awards, the 21-year-old country superstar was named Artist of the Year at the American Music Awards on Sunday night (Nov. 20).

"This is one of the craziest things that has ever happened to me," the singer, astonished by her big win, said upon accepting the trophy. "To be nominated alongside artists I'm a superfan of ... oh my gosh! I can't believe this is happening to me ... Thank you so much to the fans, to the fans and also to the fans! I love you guys so much; I love my family; I love you, Selena (Gomez), the little sister I never had. I love the fans, I love my label, my band.... Thank you for everything!"

Taylor triumphed over Adele, Lady Gaga, Lil Wayne and Katy Perry for the fan-voted award. This is the 'Mean' singer's tenth career AMA victory and the second time she has won AMA Artist of the Year. She also took home the Favorite Female Country Artist and Favorite Country Album (for 'Speak Now') honors on Sunday, while Blake Shelton was named Favorite Male Country Artist and Lady Antebellum won Favorite Country Band, Duo or Group.
