According to a survey, 28 percent of men actually said that they found 'smile lines' attractive in women, reports a major newspaper.
Interestingly 52 percent women are disinterested to have their pictures taken in fear of ugly smile.
Celebrity photographer Daniel Kennedy suggested women, who are worried about their smile, to say the words 'oats' or 'plum' to 'create a really sexy shape'.
According to him, a woman should keep the chin down and look up through the eyelashes 'for a face-slimming look' and also must put lip-glosses to highlight their smile.
TV presenter Holly Willoughby's smile was the most popular among men, followed by Cheryl Cole, Katy Perry and Fearne Cotton.
