The other big winners were Lady Antebellum, Brad Paisley and Sugarland.
Swift was nominated alongside Jason Aldean, Toby Keith, Miranda Lambert, Brad Paisley and Keith Urban for the fan-voted award, the Hollywood Reporter said.
"This is the first time that I`ve ever won this, and I`m just losing my mind," Swift, 21, said.
Lambert took home four awards, including female vocalist of the year. Her single `The House That Built Me` earned honors for song of the year, single record of the year and video of the year.
