Jennifer Aniston Pictures in Marie Claire Australia May 2012

Jennifer Aniston covers the May issue of Marie Claire Australia with a photo that was recycled from an older Elle shoot. However, Jen's interview with the publication is all new. She chatted up her and boyfriend Justin Theroux's movie Wanderlust, which opens in Australia on April 25. Jen and Justin are currently hanging out together around their LA home base and were also recently spotted on a dinner date with Tom Hanks and Rita Wilson. Inside the magazine, the 43-year-old actress dished on her love life with Justin, going topless, and finally letting her guard down. Here's more from the interview with Jennifer Aniston in Marie Claire Australia:

• On her relationship with boyfriend Justin Theroux: "He's a protector, for sure. He's just a good human being, and so funny."
• On her topless scene for Wanderlust: "There are always nerves when you shoot a scene like that. But the adrenaline takes you through it and then you have the girls come in and cover you up immediately. I got very comfortable with seeing nude people, pretty much immediately. It was bizarre to know that these were actually nudists — because there's a nudist colony in Clarkesville — and how comfortable they are being nude."
• On not wanting to be so guarded: "I've really made a conscious effort to not wall myself up like that again. I built those walls pretty high in the past. I think you miss out on a lot of stuff when you're so protected and isolated."
