Sister Cristina Scuccia signed a record deal with Universal after the programme ended in June and is now working on her debut single.
The record label has released a short video of the nun, which shows her recording Alicia Keys' "No One", the song that shot her to fame on the show.
No other details of the album were given other than that it would be "coming soon".
Sister Cristina wowed the country with songs such as 'Girls Just Want To Have Fun' and 'Time of My Life'.
She had previously said she wanted to use her talents to spread the message of the Catholic Church.
