Rebecca Hall

Brit actress Rebecca Hall is a natural, striking a pose for InStyle's monochrome-themed May issue, but in our exclusive interview she opens up coping with nerves and how she's tried to keep her romance with Sam Mendes private.

While these days Rebecca counts Iron Man 3 co-stars Robert Downey Junior and Gwyneth Paltrow as friends, it seems she wasn't always a natural socialite:  "I was painfully shy as a child. Painfully. To the point where my parents would say, “Have you made any friends yet?”"

And even now she admits: "It comes back and haunts you at weird times. Rooting for change in my pocket in the newsagent, that’s when I get it.”

Despite the scrutiny her relationship with director Sam Mendes has come under since it went public, she says she's determined to try and stay schtum: "It’s what happens when you start going out with a famous person and are a bit famous yourself, I guess. It’s their problem though. Everyone can be interested but I’m still not going to talk about it.”

Though she does divulge that she "ideally" believes in lasting love.
