Knightley denies 'enhanced chest' reports

Keira Knightley has dismissed reports her image in new advertisements for fashion house Chanel has been enhanced by computer graphics, insisting her curves are all her own.

The 22-year-old British beauty, who has become the face of new fragrance Coco Mademoiselle, has always denied rumours her skinny frame is due to an eating disorder, and insists suggestions her breasts have been boosted are unfounded.
