Hollywood actress Jessica Alba only finds chivalrous men attractive, but believes such behaviour is becoming increasingly rare in contemporary society.

The Sin City beauty, 24, is dating film production assistant Cash Warren and admits he swept her off her feet with his traditional manners.

She says, "He is very smart and respectful. Guys should treat women with respect. I am still lady-like and feminine, but unfortunately a lot of men have lost their sense of chivalry. I like a man to open doors and offer to pay.

"But by no means do I need him to pay for things or tell what I should or shouldn't do. I wouldn't like that.

"I'll have the children and be a wife, but I'm also going to work."
