It was Melanie Amaro who may have been the X-Factor Season One grand winner but according to news made of how the show went, it was Justin Bieber still who took the entire stage.

The young pop superstar hit the stage with a neon green jacket to render everyone a song called "The Christmas Song." And to make it all better, Stevie Wonder and his keyboard helped out the teen icon in giving everyone a nice holiday cheer.

Right after the set of these two wonders was done, Bieber did not let the moment pass without giving much credit and honour to Stevie who has been one of his idols for a long time. He expressed sincerely all his gratitude for coming out on stage with him.

Drew Ryniewicz, the eliminated contestant of the show also performed her own version of Bieber's ever famous 'Baby' song and even tweeted her more support to continue on with her dreams. Bieber even let her have her own moment after finishing his song "Santa Claus Is Coming To Town."

Other guest stars to help pull off a successful night include Pitbull, Leona Lewis, and Pitbull.

It was definitely one Bieber-filled 'X-Factor' night!
