Making love work: “There’s nothing easy about it. We get on airplanes. You have to be willing to get on one, plain and simple. And we Skype – it’s boring, but it’s true. We don’t even sit in front of the computer. The other day, I was cleaning, he was cleaning. We couldn’t see each other – we were just scrubbing away and talking like we were in the same room.”
Kissing Julianne Moore: “Love scenes are always awkward- even in real life they can be awkward. In a movie they’re just very technical. We were both nervous, so we laughed a lot. And then the scene turned out exactly the way we wanted it. Still, I keep thinking my lips were so big in that movie! My look was all lips and all hair.”

The new issue of InStyle Hair is available now.
