Candidly admitting his own insecurities, Robert Pattinson showed fans his sensitive side in the current issue of Australia's Sunday Style.

Still a little flabbergasted by fame, the "Twilight" star shares, "I just didn't expect any of this and I didn't ask for it. It was literally all luck. I just stumbled from job to job."

With the pressure of the biz, the 27-year-old actor admits, "It's difficult to remain sane. It's really difficult. In the beginning I didn’t even notice my life had changed so massively, because I was always working. I suppose eventually I got used to it."

Speaking about his new role as spokesman of Christian Dior's new fragrance campaign, RPatz says, "I’m trying to get out of being perceived as really young and I think doing [Dior] helps along those lines. I’m 27 now and I can feel people looking at me differently. It’s a weird year. With 'Twilight' ending and other films I’ve done, like 'Cosmopolis,' I suddenly feel like I’m being treated like an actual actor.”

With all the experience he's had, the seasoned star claims he still panics on the red carpet, confessing, "I get a ton of anxiety, right up until the second I get out of the car to the event, when suddenly it completely dissipates. But up until that moment I’m a nut case. Body dysmorphia, overall tremendous anxiety. I suppose it’s because of these tremendous insecurities that I never found a way to become egotistical. I don’t have a sixpack and I hate going to the gym. I’ve been like that my whole life. I never want to take my shirt off. I’d prefer to get drunk.”
