Frowning fellas versus grinning gals
The study from the University of British Columbia is clear -- 'smiley' guys are at a serious disadvantage when it comes to initial attraction, while single girls need to turn on the charm and send out some happy vibes. Applying this research to some well known faces, the celeb role models men and women need to study include:

Smouldering? He's like a Leeside Mount Etna.
The Scottish golfer, cruelly dubbed 'Mrs Doubtfire' by US fans who claim he resembles Robin Williams's stern Scottish nanny character, may actually be projecting serious sex appeal. Or extreme grumpiness.
Her ongoing man problems are a mystery since the former Friend is all about the perkiness.

Seldom seen without a million-dollar smile.
That smile! That derriere!
Talent and a beguiling, girlish smile.
