After months of grueling competition, ‘The X Factor (US)’ will reach its climax this week and Simon Cowell has promised that it will be the biggest finale event that he has ever constructed. In fact, in addition to several guest performers, the head judge also announced that three “mega superstars” will be performing with the top three contestants!

Justin Bieber, Leona Lewis, Pitbull and Ne-Yo have all been booked to hit the stage on the ‘X Factor (US)’ on December 22nd. Moreover, finalists Melanie Amaro, Chris Rene and Josh Krajcik will each sing a duet with a surprise act, two of whom are still in negotiations to be added to the show’s setlist.

Interestingly, Justin Bieber is expected to perform with two artists whose names have yet to be revealed. Why is that notable? Well, Justin Bieber worked with Mariah Carey on a remake of her classic hit ‘All I Want For Christmas Is You’ and the diva had been confirmed to appear on ‘X Factor (US)’ since the beginning of the season. Furthermore, contestant Melanie Amaro has expressed that she wants to duet with Mariah Carey who she described as her “role model.”
