Jennifer Lawrence shines in a yellow Marc by Marc Jacobs dress on the May 2011 cover of Teen Vogue magazine.

The 20-year-old actress opens up about The Hunger Games, her time in London and her good girl nature. Check it:

On nabbing the coveted role of Katniss: “She’s incredibly powerful, brave, and tough—and yet she has a tenderness and complexity. It was very humbling hearing that Suzanne [Collins] and Gary [Ross] feel that I embody those traits.”

On filming X-Men First Class: “”I had a blast. I was living in London for five months, and the whole cast . . . we all legitimately love each other. We got addicted to hanging out.”

On being a good girl: “Sometimes I get anxiety about not staying up late enough. I’m not the one in the corner, but if anyone was like, ‘I want to go home and watch The Big Lebowski,’ I’d be right there with my hand up.”
