A singing nun shocked the judges of the Italian version of The Voice during the show’s blind auditions.

The 25-year-old nun wore the traditional outfit for a nun, but the judges couldn’t see her, as they all had their chairs turned. Still, they were immediately impressed with her vocal power as she belted out Alicia Keys’ “No One,” notes Fox News. The crowd also roared the second she started singing.

When the judges turned around to see her, they were shocked to discover she is a nun. Her name is Sister Cristina of Sicily, reports the Daily News.

She told the judges, "I have a gift and I'm giving it to you."

"If I had found you at Mass I would always be in church,” rapper J-Ax told her. “You and me are like the devil and holy water.” The other judges on the panel are Noemi, Piero Pelù and Raffaella Carrà.

The performance aired in Italy on Wednesday and has already become a global viral video. It’s been seen over 3.1 million times on YouTube.
