She said: "I have a rule. No actors. I have dated an actor before, at Juilliard, 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."
The 35-year-old beauty finds it "boring" talking about her acting work with potential lovers, but she enjoys discussing films with boyfriends in the same way as a 15-year-old fan of big screen productions.
She added in an interview with Britain's InStyle magazine: "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."
