The 35-year-old said she has a rule when it comes to relationships - refusing to date fellow actors.

Explaining she once dated someone in the business while she was at drama school, the "Zero Dark Thirty" star says being in the public eye constantly freaked her out.

"I have a rule. No actors. I have dated an actor before, at Juilliard drama school, but since then, I've only been on a couple of dates with one and I was so freaked out someone was going to take a picture of us, because they were famous.

"I realised I wanted just to be able to hang out with someone. And I didn't want to talk about the business, first of all. I love movies. But I love talking about them like when I was 15 years old. I'm a film fan, but I don't want to talk about auditions or what movie I'm gonna do. I find that so boring," she said.

The redhead remains guarded about her current beau, only divulging that "some people in the fashion world" know who he is.

The actress also explained that she has no interest in becoming a Hollywood legend as fame and money have never been her goals.
