Amanda Seyfried is attracted to ''creeps''.

The 27-year-old actress - who previously dated Dominic Cooper - can't help wanting to date ''interesting and mysterious'' guys, even when they're no good for her.

She said: ''Unfortunately, there's something attractive about someone who's broken, for me, and a lot of women that I've spoken to.

''My best friend and I are attracted to creeps - sometimes.

''They're interesting and mysterious and they provide us with this rush and this need to chase or fix - just these needs they fill in yourself. It doesn't make any sense. It's a weird psychology but unfortunately it's the way the world works.''

Amanda - who can next be seen in 'Lovelace', a biopic of tragic porn star Linda Lovelace - believes American cinema is going through a ''sexual revolution'', with more liberal attitudes to what is seen on screen.

She added in an interview with the Daily Mirror newspaper: ''Sex in movies shouldn't be as big a deal as it is. Guns are huge in American cinema, but with sex everybody is so prim about it here.

''[But] something is changing in American cinema. We're going through some kind of sexual revolution right now, I'd like to think.

''Everybody does it [has sex]? Who doesn't do it? So why are we shying away from it so much?''
