Four will enter, but only one will leave on the finale of The Voice Tuesday night, with season 17 coming to a close in a true four-way battle between the judges.
Blake Shelton, Gwen Stefani, Kelly Clarkson, and John Legend each have a team member left heading into the final frame, and they are all calling in some next level talent to help push them over the top.
Katie Kadan from Legend's team will get a special assist from Adam Lambert, joining her for a performance of “Believe.” The pair will sing the song which Lambert first performed in front of Cher at the Kennedy Center honors last year.
Lambert recently told RADIO.COM about the nerves heading into that moment, with the icon watching him on stage. "I don't get that nervous that much these days so I was like 'oh shoot I'm nervous' and midway through my hand was shaking,” he shared. “It made for a vulnerable moment which was great."
