Sister Cristina Scuccia wowed judges and audiences again earlier this week on The Voice of Italy. People first took notice of the 25-year-old nun in March after she performed a jaw-dropping rendition of "No One" by Alicia Keys during her audition on the reality singing show. Her powerful vocals brought judge J-Ax to tears, and a video of her performance went viral online. Scuccia stunned again on Wednesday in the show's first Battle round, and emerged victorious against 23-year-old Luna Palumbo. The two women performed "Girls Just Want to Have Fun" by Cyndi Lauper, and Scuccia had her sisters dancing and cheering as they watched her energetic performance from the sidelines. "She unlocked the next level like in a video game," Scuccia's coach J-Ax said of her performance. "She is now Mother Superior... When Sister Cristina sings she gives joy, and this is her gift."
