The clues: In the clue video, there was a shot of a gold member card as well as a leopard. They also talked about going through "extreme seasons" in their life and how they were once the centre of the universe before they got burned out. At one point, the earth and trees came together to make a Mickey Mouse logo. Maybe it's a former Disney star?
Who it could be: While some popular guesses from the judges were Demi Lovato and Katherine McPhee, we think it could be former Cheetah Girls star Kiely Williams based on the voice. Maybe that leopard in the clue video is actually a cheetah? Some other popular theories seem to be Christina Aguilera and LeAnn Rimes.
