Cristina Scuccia, 25, appeared on the Italian version of the show dressed in her habit and blew judges away with her rendition of the Alicia Keys tune 'No One'.
Cristina's impressive recital hit the 30million mark on YouTube in just seven days – breaking a new record!
While 'Gangham Style' remains as the most-watched video on the website, it took 18 days to reach over 10million hits, meaning Cristina has achieved record-breaking success.
Even Alicia Keys expressed her approval of Cristina's cover, tweeting: "Now THAT'S what beautiful, pure energy looks like! Sing it, sister Cristina! ;)".
Judges on the show were also dazzled by Cristina's singing, with one asking if she was a real nun.
The Ursuline sister replied: "Very real indeed. I have a gift and I've come to give it to you."
