Alicia Keys' 'No One' song, a former top-ranking hit on the billboards, was surprisingly sung by a nun on the show 'The Voice of Italy'. The 25-year-old nun unexpectedly sung Alicia Keys' 'No One' song on Wednesday's episode of the show. She not only stunned audiences, but the judges as well, and quite possibly will stun anyone who will see her performance.

The name of the nun who sang Alicia Keys' song 'No One' is Sister Cristina Scuccia. She took the stage on 'The Voice of Italy' while wearing her habit and she just belted out Alicia Keys' 'No One' like there's no tomorrow. Not only that, Sister Scuccia even matched the song with some dance moves.

In reaction to her rendition of Alicia Keys' 'No One' hit song, the surprised studio audience gave the talented nun a standing ovation and a four-chair turn from the coaches. Her fellow nuns cheered their friend on backstage throughout the audition.

Of course, the coaches' reactions are way better than that of the audiences as they became flabbergasted when they turned around and saw who sang Alicia Keys' 'No One' song. What they saw was a demure nun who was completely opposite from her powerful performance.

Coach Noemi told the Sister Scuccia, "When I turned around, I thought I had a vision problem." Coach Pelu agreed with Coach Noemi and said, "I still have not woken up from when I turned around. You're amazing."

TODAY show hosts Tamron Hall and Savannah Guthrie were all compliments as well on Friday about the nun's rendition of Alicia Keys' 'No One'. "She was killing it." said Tamron Hall, while Savannah Guthrie said "Not since Mother Superior have we seen such talent!"

Sister Cristina chose to give audiences another surprise with her choice for a coach, because she selected rapper J-Ax as her coach. This she apparently did because the rapper was moved to tears by her performance and was the first one to turn his chair.

According to the website of 'The Voice of Italy', Sister Scuccia has dreamed of being a singer since childhood, and her superiors are the ones who made her audition for the singing competition.

Alicia Keys' 'No One' is a powerful song simply sung by the original singer, but nobody was expecting the surprising turn of events in 'The Voice of Italy'. Who would have thought a nun is a fan of the song and that she could sing it just as well?
