Jessie J is offering one of her fans the chance to sing a duet with her.

The lucky fan will get the opportunity to sing with the 'Domino' star via MasterCard's Priceless Duets competition.

The giveaway is run in conjunction with the BRIT Awards, which this year sees Jessie J nominated for three awards. Speaking about the duet competition, Jessie J told the Daily Star:

"It's important to surprise people and to be part of something that I’ve always been about. It's not about the money, it's priceless. Moments like this are magical and make people's day. The BRITs and Mastercard are something I want to be part of. These fans make me able to be at the BRITs – to be making music and to give something back is the most important thing."

Those wishing to enter the competition have to do so via the BRIT Awards/MasterCard 'Something For The Fans' website.
