Christina Aguilera is headlining this season’s finale of The Voice. She will take the stage for a duet performance with Pitbull. The duo won’t be the only Latinos showing off their vocal talents. Crooner Bruno Mars will also perform his newest single from his album Unorthodox Jukebox. Another mega-star taking the stage is Grammy award winning Nelly. And last, but certainly not least is Cher. It will be her first live television performance in more than a decade.
