Goodbye, Panem—hello, Fashion Week! Willow Shields took a front-row seat at her favorite designers’ spring 2015 shows in New York City, and it didn’t take long for fans of The Hunger Games to spot the actress, who plays Primrose Everdeen in the film series. “I was walking around Lincoln Center, and people started yelling, ‘I volunteer as tribute!’” Shields told InStyle when she stopped by our offices last week. She filled us in on filming the latest installment in the series, The Hunger Games: Mockingjay – Part 1, which hits theaters Nov. 21.

Since first landing the role of Prim at 10 years old, Shields has turned to on-screen big sis Jennifer Lawrence for guidance. “She’s done a great job of supporting me in a way that helps to keep my life balanced while staying grounded like she is,” Shields says. “Jen has an Oscar and she’s one of the most famous people in the world, but she’s still super humble and down to earth. She’s really taught me to stay that way.”

While encouraging Shields to keep it real, Lawrence—who looks fierce as the titular Mockingjay on the latest poster for the movie—has also set a professional example with her focused work ethic. “People always talk about how Jen’s so funny, and she is. She lightens the serious on-set mood in a great way,” Shields says. “But they don’t see the fact that when they say 'action,' she’s serious about her work and portraying her character the right way. I love that about her—it’s inspiring that she can balance having fun on set while also being serious.”

After four years of filming, the bond has only grown between the on-screen siblings. “She really is like a sister to me, and when my mom’s not traveling with me, she’s like a mom to me,” Shields says. “She’s so protective over me, and somehow we’ve become even closer while filming Mockingjay, which I didn’t know was possible!”
