The Black Swan stunner is frequently hailed as one of the sexiest women in Hollywood, and recently came runner-up in Maxim magazine's Hot 100 list behind Leonardo DiCaprio's supermodel ex-girlfriend Bar Refaeli.
But the Ukrainian-born star reveals she never pays attention to praise for her looks, because she'd rather concentrate on proving herself as an actress in an industry saturated by beautiful people.
She tells Britain's The Sun, ""I appreciate the attention but I don't think of myself as particularly attractive at all. I also don't have that naturally sexual or sensuous way of behaving that some women have.
""L.A. is filled with the most beautiful women in the world who all come here to be part of the entertainment industry.
""It's impossible to compete against that. Some women rely on their looks to make it and others know that they need to work hard to not just be treated as a pretty object and have a serious career.
""So I've never bought into my own beauty myth and I have always worked hard and believed in myself as an actress in order to get where I am.""
