Are you ready for Leona Mania?

Ready or not, here she comes!

Leona Lewis' new single 'Happy' will premier this sunday on Radio One in London and by the sounds of the reviews from the people who were lucky enough to hear it, It will be a Worldwide hit!

Leona's upcomming album will be called 'Echo' and will have more of a live sound to it, We heard some of the songs what leaked (Not sure if they will be on the album or not) but they sound fab!
