Leona Lewis 'Happy'

From North London girl to genuine global star - it's been a busy couple of years for Leona Lewis.

Back in June she had the audience of 55,000 at Capital's Summertime Ball on their feet. She's now returned the favour and gave Capital the first play of her new single, 'Happy'. Taken from her forthcoming album,  'Echo', due in November, which she's been working on with Justin Timberlake, Ne-Yo, Ryan Tedder and producer Timbaland.
