Kristen Stewart looks breathtaking in Gucci on the October issue of British Vogue.

Robert Pattinson's former girlfriend doesn't talk about her troubled love life, but she does give her thoughts on having a hard time keeping cool in Hollywood.

    "I know if you haven’t thought about how you want to present a very packaged idea of yourself then it can seem like you lack ambition. But, dude, honestly? I can’t. People expect it to be easy because there you are, out there, doing the thing that you want and making lots of money out of it.

    But, you know, I’m not that smooth. I can get clumsy around certain people. Like if I were to sit down and think, ‘OK, I’m really famous, how am I going to conduct myself in public?’ I wouldn’t know who that person would be! It would be a lot easier if I could, but I can’t.”

The 22-year-old actress recently admitted to having an affair with married Snow White and the Huntsman director Rupert Sanders. KStew adds: “There is always going to be that seam of people who want things differently to the standardized version. It’s not necessarily a rebellious thing, it’s just who they are."
