The Oscar-nominated actress talked making it in tinsel town and her celebrity dating rules. On breaking Hollywood Jess said, "There were a couple of times when I thought, 'Maybe I should dye my hair blonde?'."
"I'm in LA and I'm thinking, 'Why can't I get an audition for a film?' Being a redhead and not having very conventionally modern looks, it was confusing for people and they didn't know exactly where to put me."
Well, the stunning red locks worked like a charm for Yves Saint Laurent who made Chastain the face of its new fragrance, Manifesto, in August.
The star also confesses she'd never strike up a relationship with a fellow actor. "I have a rule," she explained.
"No actors. I have dated an actor before... 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."
Although Jessica didn't divulge whether she's currently seeing anyone she revealed, "If you fished around enough, you could find some information. To be honest, I never talk about it. Some people in the fashion world know, though."
