Who would have guessed that a nun knows how to rock?

Sister Cristina Scuccia, age 25, confidently took the Voice of Italy stage and completely wowed the judges with her spirited rendition of Alicia Keys' top hit "No One". Sister Cristina wore her traditional nun attire for the show, including a habit and a large silver cross. As the Sister belts out her song, the camera pans to backstage to show a trio of nuns cheering Sister Cristina on as they jump up and down. The judges sit, backs facing the Sister, and the shock is evident on their faces when they turn around to see what the singer looks like! The Huffington Post reports that the nuns are from the Ursuline Sisters of the Holy Family in Sicily.

Unfortunately, the song is the only part of the video that's in English, so it's unclear what the judges and Sister Cristina say to each other in the portion after she sings. The New York Daily News reports that sometime during their talk one of the judges, Italian rapper J-Ax, jokes, "If I had found you at Mass I would always be in church. You and me are like the devil and holy water." Sister Cristina is also asked what the Vatican would think of her talent, to which she responds, "I hope that Pope Francis will call me now."
