London: Susan Boyle has picked a complete unknown person to sing on her latest album.
Susan, who shot to fame last year after appearing on Simon Cowell`s TV show Britain`s Got Talent, announced medic Amber Stassi as winner of her YouTube contest called Susan`s Search.
Lucky American Amber was one of tens of thousands of aspiring stars hoping to win a chance to sing alongside the multimillionairess.
She recorded a video of herself performing Christmas carol Silent Night in her greenuniform behind an ambulance in a work break.
"I made my tape at work when I had a little time on my hands," the Daily Express quoted mother-of-three Amber from near New York as saying.
"Never in my wildest dreams did I think I would win," she said.
Amber would sing a duet for Boyle`s forthcoming album `The Gift,` which will include festive songs.
Susan said: "Amber really stood out for me. She has a lovely, very beautiful voice."
