Leona LewisLeona Lewis credits the honesty of her family and friends in stopping her getting swept away by her sudden fame.

The X Factor winner, who is teetotal and prefers to not wear clothes that “show off your bits”, told Parade recently that it would have been all too easy for her to have become wrapped up in the idea of being a celebrity: “A performer’s privacy is taken away. The media are always there. You can’t make your mistakes in private.

“[But] I have the advantage of a great support structure.

“I get honest opinions from my family and friends. They aren’t always telling me what I want to hear, but the truth helps keep my head straight.”

But she added that comparisons to A-list pop divas such as Mariah Carey and Whitney Houston are “amazing”: “It’s exceedingly gratifying, because they’re so great.”
