Yana is for Y – the Czech model who turned into an Indian actress – http://en.wikipedia.org/wiki/Yana_Gupta
Am not a fan of Yana, though she being a vegetarian is a good factor to impress me. Being in show business, she has done well as an author of the health book. For a women of her age, she has managed her life and career well.
She has been on many modelling assignments with impressive labels like Calvin Klein, Sony, Lakme, Honda, Toyota, etc.
She is probably one of the few (or the only one?) Western Caucasian women to get into India film industry.
