London: Opposites attract, right! A report has revealed that good girls really do find moody bad boys sexier than cheerful chaps. Psychologists also say that brooding or swaggering males were far more alluring than happy men who smiled a lot.

In contrast, men were more attracted to smiling women compared to as straight-faced women.

Volunteers were shown pictures of the opposite sex projecting different emotions for the study at the University of British Columbia in Canada.

Researchers said evolutionary theories suggest a confident, proud posture in a male exaggerates masculine features, implies status and an ability to provide for a partner and offspring.

Smiling was associated with a lack of dominance in men and 'submissiveness and vulnerability' in women.
