"It's crazy, right?" she tells the December issue of Maxim, out Nov. 17. "I think my dog is more famous than a lot of stars out there. I bet some people in Hollywood are like, 'I can't get my picture in a mag, but Ashley's pooch [Marlo] does?' It's mind-boggling."
But while Greene is adjusting to the pressures of the paparazzi, she makes it clear she brought this on herself.
"Oh, my God, I wanted this part so badly! I worked my butt off for it because I absolutely love Alice, my character," says Greene. "She's sweet, sexy, and a killer! So when they told me I got it, I tried to play it all cool, you know, for about a minute."
But that attitude didn't last long. "Suddenly the Twilight blogs started picking it up, and then fans were there taking photos, and I'm on the news, and I was like, 'What?' And then I got really nervous."
So what's next? "I want to hit up James Bond," she says. "That would be awesome."
