The opera-singing duo, who finished second on the ITV1 talent show, have included a rendition of the band's hit song 'Rule the World' on their new LP Together.
Jonathan Antoine said: "This is one of our favourite songs. When we first listened to the song after we had sung it in the studio we both thought this really has to be on the album.
"We had a real connection with this song. It's not just a love song. It's universal, everybody can take something from it and it reaches out to all."
The pair's upcoming record - out September 24 - will feature brand new songs as well as covers of Celine Dion and Andrea Bocelli's 'The Prayer' and Muse's 'Unintended', which has been reworked in Italian.
"I'm still pinching myself that we are actually making our own CD," Jonathan said of the release, while Charlotte Jaconelli confessed: "This is a dream come true for us."
Fans can listen to a preview of the album tonight (September 10) at a listening party, which can be streamed via the pair's official Facebook page.
