It's been weeks of hard work and nerve-wracking eliminations, but the time has finally come to find out who was crowned the winner of "The X-Factor" season three.

The final three,Jeff Gutt, Carlito Olivero and Alex & Sierra, all nailed perfect performances on Wednesday night, but only one could score the most votes and take home the $1 million recording contract.

Leaving it to be a nail-biting episode, the duo of Alex & Sierra were officially named the winners! "We're speechless," Alex said, "I don't even know ... this is incredible. Thank you everybody that's voted."

"Thank you so much for getting us here and thanks for not making fun of my weird faces all of the time," Sierra added.

Aside from the winner's excitement, the audience and eager viewers at home were in for another treat on tonight's episode as "Glee" star Lea Michele performed her brand new single, "Cannonball."
