She's one of the luckiest girls ever!!! Eva covers the October issue of Lucky magazine where she opens up about her career, her fashion, and (sigh) refers to Ryan Gosling as her "boyfriend." When Mendes was getting ready to shoot "A Place Beyond the Pines," she dropped some serious weight for the role ... and her mother was not a fan. "I’ll do anything for a role. For 'A Place Beyond the Pines,' I exercised a lot. I wanted my character to feel really depleted. My mom didn’t understand why I would want to look that way. She’s constantly telling me I’m too skinny," she reveals.
