Cheryl Cole is the most photogenic woman ever.
A spokesperson for Nikon, who commissioned the study to promote their new D300 camera, said: "Cheryl Cole was a clear winner and is loved by the nation for her looks, dress sense and friendly nature."
Cheryl, 26, has previously admitted that style plays a big part in her self-confidence.
Commenting on the infamous David Coma black and metallic dress she wore while on UK TV show 'X Factor', the Girls Aloud star suggested it wasn't a personal favourite.
She said: "The alloy wheels dress was a bit of a disaster, but Beyonce had it on a couple of days later, so it can't have been all bad.
"What I feel like in a dress is more important than how I look."
