Melanie Amaro Wins X Factor! [VIDEO]

The last night of X Factor went out with a bang!  A sea of superstars were on hand to celebrate the shows big night.  Everyone from 50 Cent to Stevie Wonder was in the building, as Melanie Amaro was crowned the big winner.

The win comes with a five million dollar recording contract and her own Pepsi commercial.  During the finale she treated the audience to a little holiday cheer singing Mariah Carey's "All I Want For Christmas Is You".  Justin Bieber treated the crowd to "The Christmas Song" and "Santa Claus Is Coming To Town" with a little help from Stevie Wonder who played the Hamonica on the side of the stage.

Leona Lewis also took the stage, singing "Run", Pitbull and Neyo came through and did "International Love"/"Give Me Everything" with X Factor alum Marcus Canty.  Finally, 50 Cent rapped it up performing "Wait Until Tonight", bringing out former X Factor rapper Astro and a group of L.A. Lakers for an assist as he brought the house down with "In Da Club".  Wow, what a night!
