Sister Cristina, the Italian singing nun sensation

Sister Scuccia

The cliche 'voice of an angel' has been worn thin by reality TV talent shows. But Sister Cristina Scuccia, a 25-year-old member of the Ursuline Sisters of the Holy Family, has a unique claim on the mantle, reports The Sydney Morning Herald.

Scuccia has become a global phenomenon after only one appearance on The Voice of Italy, the Italian version of the hit talent format The Voice. In her audition, she performs the Alicia Keys song No One and is so impressive the audience give her an immediate standing ovation and all four coaches turn to face her.

In the last 24 hours, clips of the performance have gone viral on the internet.

According to The Voice format, the four coaches do not see the performers during the 'blind audition' phase - they sit with their backs to them - and by turning their chair to face the singer, make a commitment to mentor them trough the next round.

If more than one coach turns, the performer must choose which mentor to work with. As the coaches - singer/actress Raffaella Carra and singer/songwriters Noemi, Piero Pelu and J-ax - turn and face Scuccia, their shock escalates.
