The X Factor USA aired its finale performance show of the second season tonight December 19, 2012. Each of the top 3 finalists performed three songs. Who do you think will win X Factor USA? If you like to see any of tonight’s other performances, click here!

For their first song, Fifth Harmony sang the song that may have changed their destiny forever: An encore of “Anything Could Happen” by Ellie Goulding. And just like the first time they performed this song on the X Factor, magic happened again.

LA Reid said he is completely shocked because Fifth Harmony were the underdogs but now, they’re “the ones to beat.” He also said he did not know how Simon has done it because he never thought this could work when he first saw the girls perform and now the girls are sensational. Britney Spears liked the song choice and said they were spectacularly girly, and just fun! Demi Lovato praised them for working so hard and said she was very impressed. She hopes America gets behind them and votes for them. Simon Cowell thinks it would be very special if they won the competition. Of course Simon–they’re your creation. But you know what? Simon is right. These girls killed it Wednesday night –the underdogs they no longer are. Sensational popstars is who they will be very soon.
