After going viral on YouTube and surviving months of competition on Italy's version of "The Voice," it all comes down to tonight for Sister Cristina, better known as "The Singing Nun."

The 25-year-old nun from Milan is considered by many to be the front-runner going into tonight's finale of the reality TV singing competition.

"No one has won yet and there are still four of us competing, but regardless of how I do, my superiors make decisions about my future," Sister Cristina was quoted as saying by Italian media, adding that, even if she gets a record deal, she'd "be happy to go back to singing in chapel."

The nun first made headlines in March when she performed "No One" by Alicia Keys on the show. The YouTube video of her performance went viral, garnering over 50 million views, and a supportive tweet from Keys herself.

Sister Cristina's winning streak on "The Voice" was fueled by her performances alongside unlikely singing partners including Ricky Martin and Kylie Minogue. Last month, Sister Cristina performed a high-energy version of "What a Feeling," complete with her fellow sisters dancing in the studio audience.

Sister Cristina, who is coached by Italian rapper J-Ax, wears her habit and crucifix onstage and has said she was inspired to audition for "The Voice" by the words of Pope Francis to "get out onto the streets."

"I have a gift and I am giving it to you," Sister Cristina told the judges in March during her blind audition.

Tonight's live finale will include performances by the British band Clean Bandit and Australian rock group 5 Seconds of Summer, according to the U.K.'s The Telegraph. The winner will be announced around 1 a.m. local time.
