A new single?
Yes actually, but despite her massive success in the pop charts, the X Factor winner said she wants to change tack; and move into opera. Lewis, 27, made the No1 spot in more than 30 countries with Bleeding Love. She's also a three-time Grammy Award nominee and was the world's best-selling new artist in 2008.
Tired of the limelight then?
Not exactly. She's been big on opera for a while. She trained at the Ravenscourt Theatre School and the Italia Conti Academy, where she says opera is what she always wanted to do. She said she would love to sing Lakmé, a 19th-century French opera set in India.
So we'll hear Leona singing in French soon?
Lewis reckons she'll have to train for at least a year before she could enter opera. "It's a different way of using your voice... I'd have to go in full-on if I did it," she said.
Great, but what about the new song?
"Trouble" was out yesterday and made its radio debut in August. It's co-written by Emeli Sandé, another darling of the UK pop scene. The lyrics tell of a failing relationship and there's a guest rap from Childish Gambino. The album, Glassheart, is out next week. It's her third LP but some reviewers have criticised its familiar sound.
