DO IT YOURSELF! 'Beauty is in the SMIZE of the beholder' says a post on Tyra Banks's Facebook page. Screen shot from iTunes

MANILA, Philippines - On December 30, supermodel, modeling guru and entrepreneur Tyra Banks guested on USA TODAY's Talking Your Tech segment to teach us her now-famous "smize" or smile-with-your-eyes.

The guesting is part of her promotional campaign for her new Smize Yourself! app, now available on iTunes.

According to the app's decription on iTunes, Tyra will even cheer you on as you attempt to smize like a top model.

Sounds like a dream come true for aspiring models and also for self-portrait-takers. As Tyra would say:
