Emeli Sande is taking part in a new competition which will allow one of her fans to sing with and star alongside her in a TV ad.
The 2012 BRITs Critics' Choice Award winner is one of a number of celebrities who have teamed up with MasterCard for their 'Something for the Fans' Priceless Duets initiative which also includes Labrinth and JLS.
Emeli said: "Singing a duet is such an exciting experience. It's great to be able to share that experience with one of my fans. To be able to sing with someone that has supported me is such an exciting opportunity; I can't wait to meet them!"
Marvin Humes, from JLS added: " We are looking forward to taking on the Simon Cowell role and being the judge! We can't wait to sing with the winner and make them an honourary member of the band for the day!"
Shaun Springer, Head of Brand and Sponsorship, MasterCard UK & Ireland said: "To celebrate our long standing partnership with The BRIT Awards, this year we wanted to build on the success of last year's Something for the Fans campaign. Offering music fans the chance to have a Priceless Duet with their idols, enables us to really give something unique back to true music fans.
The competition - which will also see winners receive a pair of VIP tickets to the BRIT Awards ceremony and official after party - launched yesterday (10.01.12) and new artists will be announced before it closes on 25th January 2012.
