British pop star Jessie J has launched a competition to give one lucky fan the chance to sing a duet with her.
The Price Tag hitmaker will surprise the winner of the Priceless Duets contest by turning up unannounced to perform their collaboration - and she admits she can't wait to give away the prize.
She says, "Moments like this are magical and make people's day. (It is) something I want to be part of. These fans make me able to be at the BriTs (Awards) - to be making music and to give something back is the most important thing."
The contest is being held in conjunction with the 2012 BriT Awards, which will take place in London on 21 February (12).
