Hollywood actress Keira Knightley has admitted that she is attracted to guys who can show their emotions and cry.

"On screen these days, you rarely see a big, strong man. You see slender, androgynous-looking boys. For me, the most manly thing a guy can ever do is to cry because he is one who is in touch with himself".

Twenty-four-year-old Knightley, who is dating her Pride and Prejudice co-star Rupert Friend, also insists that she would never have an affair with any of her co-stars because they do not view her as a potential lover.

She said "I could never have an affair with any of my leading men. They always turn into brothers. I am a classic 'turn-them-into-brothers' kind of girl".
