Leona Lewis: 'I haven't had a boob job'

Leona Lewis has reportedly dismissed speculation that she has had cosmetic surgery.

The 24-year-old popstar, who allegedly turned down the chance to appear in Playboy magazine, has slammed rumours that she went under the knife for a breast augmentation procedure.

The 'Bleeding Love' singer has shown a fuller figure over the last few weeks, but Lewis has insisted that her appearance is all natural, reports Contactmusic.

She said: "Every few months, I get people asking me if I've had a boob job. No, I haven't.

"With me, every time my weight goes up or down a little bit, it's so noticeable there and people start to speculate about it. But, no, they aren't fake."
