Did you catch Leona Lewis introducing the first official play of her new song Happy on BBC Radio 1...

...on Sunday afternoon? If not, don't fret as it'll be all over radio soon!

If you heard it, what do you think? - another sure-fire hit for the X Factor winner or will you be giving it a miss?

Leona looking happy earlier this year!

Are you looking forward to Leona's second album, Echo, which is set for release on 17 November?
