Miley Cyrus, Alicia Keys Duet with Contestant on 'The Voice'

On Sunday, The Voice aired a special half-hour season 11 preview featuring its new coaches Miley Cyrus and Alicia Keys. The two coaches are the newest addition to the show and they were blown away by some of the young talent auditioning, including Darby Walker. Walker auditioned by singing Ben E. King's "Stand by Me." Cyrus, Keys, and Shelton all turned around for her. That left the coaches to fight it out. Miley Cyrus wanted her on her team so bad that she joined the singer on-stage to sing a duet of Dolly Parton's "Jolene." However, she faced stiff competition from Alicia Keys. Walker said, "When I was 10 years old, 'No One' used to be my song. I used to belt that out. My 10-year-old self would be freaking out right now." Not to be outdone by Cyrus, Keys also joined the singer to sing a duet of "No One." Though Walker chose Cyrus, it seems the entire experience was impressive to her. She said, "I just sang with Miley Cyrus and Alicia Keys, and I'm still processing the fact that that just happened. "
