Keira Knightley claims she can be a ''duplicitous and manipulative'' person.

The 27-year-old actress is aware of her more unappealing personality traits and admits she shares the same deceptive qualities as her character Anna Karenina from the film of the same name - which is based on Leo Tolstoy's 19th century tragic love story about a Russian princess who falls in love with a cavalry officer.

Referring to Anna, Keira told Canadian fashion magazine FLARE: ''There are aspects of her that I don't like. Then you go, 'Am I any better?' I am duplicitous and manipulative and all those things. Hopefully that doesn't define me but they are parts of my personality.''

Keira is also a very stubborn person, but she believes this trait has helped her in her life.

The British screen beauty claims she was constantly pestered by the ''horrible'' paparazzi in the early part of her career because they wanted photographs of her drunk but she refused to give them the shot they craved.

Keira - who is engaged to Klaxons musician James Righton - said: ''When I was very young, I was hounded by these hideous men. What they wanted was the picture of me falling out of the club. They weren't going to get that out of me. No, I chose very, very deliberately not to, because I couldn't bear the idea of giving in to them. It takes a stubbornness.''
