The 'Bad Romance' singer is astonished by the success of the Scottish star – who became a worldwide sensation after appearing on UK reality TV talent show 'Britain's Got Talent' – and hopes they can collaborate on a song in the future.
She said: "I love Susan Boyle. She is my woman of the year. She has achieved more in this year than most artists will in a lifetime. This time last year nobody even knew who she was and now she is knocking the world's most established artists off the album and singles charts.
"Our styles are different. I don't know if we could work together, but never say never. It would be great to work with somebody of that talent."
The 23-year-old US star said she had watched the clip of Susan - whose debut album 'I Dreamed a Dream' was the fastest-selling debut LP ever released by a woman - singing on the show where she surprised the judges, including music mogul Simon Cowell, with her voice a "thousand times".
She added to The Sun newspaper: "Every time I see Simon Cowell's face it makes me laugh out loud. He thinks he knows everything but even he wasn't expecting that."
The 'Paparazzi' hitmaker is not the only star to express an interest in performing with the 'Wild Horses' singer.
Rapper 50 Cent has previously said he wants to work on a track with her, while opera star Andrea Bocelli is to team up with Susan on a song for new UK TV talent show 'Pop Star to Opera Star'.
