I am siamese if you please

Has anyone noticed (or has this always been obvious to everyone but me?) in the Revlon commercials that Kate Bosworth has one brown eye and one blue eye? Not the worst deformity, but I have to say, it's pretty creepy looking. Probably not the best subject to model mascara either. The brown one's fine, it's the blue one that adds the disturbing element...it looks like a glass eye. And you know what they say about glass eyes- nothing, but only scary people have them. See for yourself.
