'30 Minute Love Affair' will be out on August 12 as the second release from Fall To Grace.
The synth-pop track recounts a real-life brief encounter Faith had with a busker in London's Leicester Square when she was just 14.
"I asked him if he'd be there the next day and he said he would. When I went back he was gone, and I've never forgotten it," she said of the story behind the song.
The singer previously released 'Picking Up The Pieces', which reached number seven on the UK singles chart.
Faith recently announced a headline tour of the UK and Ireland for 2013. She'll also play a number of shows this summer, including two headline sets at Somerset House on July 17 and 18.
