Lily Collins Is Glamour Magazine's 'Next Big Thing'

Lily CollinsWe're going to be seeing a lot of lovely Lily Collins this summer; after all, she is responsible for bringing to life the heroine of one of our favoritest favorite YA novels when "The Mortal Instruments: City of Bones" hits theaters in August. And here's where it starts! She's on the cover of July's Glamour, as the fresh face of their "Next Big Thing" issue. We love her retro-styled photo shoot—complete with red lips, bouffant hair and, of course, her famous, fabulously full eyebrows—and in the interview within, she's talking about her own next big things, from a supporting role in "Stuck in Love" to her much-anticipated turn as Clary Fray.

As for "Stuck in Love", the film is a far cry from the rough-and-tumble fantasy world of Shadowhunting—she's part of a talented ensemble cast in this indie drama by Hollywood newbie Josh Boone, who's also directing "The Fault In Our Stars." And while "The Mortal Instruments" might be the film that makes her a serious celebrity, she described "Stuck in Love" as "my most meaningful project so far."

"I fought for the role for seven months," Lily admitted. "I read the script and thought, 'No one but me can play this.' Samantha is promiscuous, cynical, sarcastic—qualities that are not me, but fun to channel. I also liked her relationship with her dad."

But don't think she's not raring for the release of "The Mortal Instruments"; Lily knows that she's got a heavy responsibility in the role of such a beloved character, and she's devoted to making fans' dreams come true.

"The fans [in Toronto, during filming] were amazing," she said. "They’d bring us cookies, mugs, tea, drawings, everything. I want to make sure I live up to their expectations as Clary."

Meanwhile, with just a couple months left before the movie hits theaters, the actress has already developed a reputation for being stylish at all times—a talent that'll only become more important as her star power (and paparazzi stalker contingent) increases. But according to Lily, she's not dressing up for the guy hiding in the bushes with a camera.

"I love fashion and always have something put together, but I won’t wear anything specifically to be photographed in," she said. And the only thing she has changed in order to be camera-ready?

"I have become more cautious of making funny faces in public."

Which is disappointing, but hey, that's what we have Jennifer Lawrence for.

Which of Lily's summer movies are you most excited to see?
