'Good Day LA': Simon Cowell Confident In Melanie Amaro, Talks 'X Factor' Guest Performers (VIDEO)

While a lot of discussions have begun about the next season of "The X Factor," there are three more contestants and still a week yet to go in this inaugural season.

Creator and mentor Simon Cowell sat down with "Good Day LA" (Weekdays, 9AM ET on Fox) to talk about the chances for his remaining contestant, Melanie Amaro, facing off against Josh Krajcik and Chris Rene.

"She will be amazing on Wednesday and she's the right person to win," Cowell said of Amaro. "But I don't rule out Chris." As for Josh Krajcik? "I don't know what he knows that I don't know, but he's very, very, very confident."

Cowell then talked about guest performers, nixing rumors that Mariah Carey had asked for too much money to perform alongside Amaro. All he would confirm, however, was Justin Bieber. "You'll have to wait and see ... because I'm not going to tell you," he said of the other singers who will be pairing for duets with the finalists.

"The X Factor" life performance finale airs Wednesday, December 21 at 8PM ET, followed by the live season finale the next night at 8PM ET.
