Lawrence has always been a girls' girl, as her Lenny letter about the gender wage gap proved last year. The piece was written in response to the Sony hack, which revealed Lawrence had earned substantially less than her male co-stars in 2013's American Hustle. Published just before The Hunger Games: Mockingjay – Part 2 hit theaters (and smashed records), Lawrence's essay started a major discussion about equal pay. "As women we don't know we're at a deficit because we have vaginas. It wasn't until they had a headline like, 'Even though she's a woman!' And I was like, 'Oh. I didn't know to be looking out for that," she says, joking, "How did I do it, getting a period once a month?" Humor aside, Lawrence says, "I think there was this studio mentality for a long time that women and girls can relate to a male hero, but boys and men can't relate to a female hero. But that's simply not true. And so we've fortunately proved that."
Writing the letter "was scary," she admits. "I keep going back and forth on being opinionated. I completely agree when there are actors who say, 'Actors should stay out of politics. We're not politicians.' My business is based on everybody buying tickets and seeing my movie...It's not smart, businesswise, to be opinionated. But then what's the point in having a voice at all if I'm not going to use it for what I truly believe in?"
Lawrence had already learned how to use her voice before, when she spoke to Vanity Fair in 2014 about having her nude photos stolen and distributed on the internet without her consent. Rather than apologize, she deemed the situation a "sex crime" and made people rethink the way such stories were handled. "If I was quiet, it would have seemed like I was ashamed. And I wasn't ashamed; I was enraged. Not once have I felt like I 'learned a lesson.' I didn't do anything wrong!" she says. "Even I've defended myself by saying I was in a relationship with a wonderful man [
Nicholas Hoult] for five years. But even if I wasn't, even if I went on a date with a guy—it doesn't matter what the situation is. It's your body. And you can do whatever you want."
