The 25-year-old Catholic nun sang her rendition of Alicia Keys' “No One” and not only impressed the judges, but also the studio audience.
After her song was finished, Coach Raffaella Carrà asked Cristina is she was really a practicing nun in the convent.
"Yes," the excited singer said, per Catholic News Agency, "I am truly, truly a sister. I came here because I have a gift, and I want to share that gift. I am here to evangelize."
Cristina chose J-Ax, an Italian rapper as her coach and said, "because I told myself that if they turned around, I would choose the first one."
He responded by joking, "If I had found you at Mass I would always be in church.
