Cole won the show with Alexandra Burke last year and is hoping to achieve the same success with her acts this year.

A source told Heat magazine: “She’s determined that one of her acts will win again this year and is already planning to perform a duet with the winner after the series.

“She’s even speaking to the rest of Girls Aloud about doing a charity single with the winner when they get back together next year.”

They added: “She’s really keen for them all to work together and to continue making sure her acts are a success even after the show has ended.”
