Alex Kinsey and Sierra Deaton, both 22, were fan favorites from the start, and were mentored by head judge Simon Cowell. On the show he said, "I feel like Christmas came early ... Thank you, America!"

The duo sang "Say Something" by A Great Big World for their final performance, but also shared the stage with Lea Michele, One Direction, Mary J. Blige, Pitbull and Ke$ha, who all performed during the season finale.

Alex & Sierra are the first duo to win "The X-Factor" in the U.S. Sierra, who seemed stunned by the outcome thanked viewers and said, " Thank you so much for getting us here and thanks for not making fun of my weird faces all the time."
