Simon explained, "I think this will be the closest finals that I've ever been involved in. I think anyone can pull it off on the night and I'm still going to be backing my girls to win this."
As for her duet partner, 13-year-old finalist Carly Rose Sonenclar shared, “LeAnn Rimes is singing with me and I'm very excited about that. I think she is amazing and her voice is really, really special. I'm psyched."
Meanwhile, Tate Stevens will team up with Little Big Town, an arrangement LA Reid is looking forward to. “It’ll be a bonfire,” he exclaimed.
And Fifth Harmony will be joined by a certain “Skyscraper” songstress. Simon noted, "It's kind of irritating to say but the person we decided to duet with is Demi Lovato. But then again she didn't have much else to do on the show because she hasn't got anyone else in the finals, I felt that she needed something to do. And after listening to your constant carping on about my contestants, the fact that I can now judge you, I can't wait."
