GUESS WHICH SUPERMODEL THIS IS?

This is a picture of Natalia Vodianova. Yes, really.

There is an ever-growing list of models who have turned their hand to acting, but the Russian supermodel surely wins the prize for biggest transformation.

Natalia stars in the soon to be released adventure film, Clash of the Titans. And, as you can see, she's not playing a beautiful sidekick or love-interest. Instead she's had the full CGI treatment to transform her into Medusa, the snake-headed demon who turns all who look at her into stone (pictured). We wonder if she was channeling any particularly terrifying editors or designers for the part?

Watch her performance in the movie below.
