Happy Birthday, Shailene Woodley! The young star celebrates her 22nd year today, and we’re predicting it’s going to be one of her most memorable one’s to date thanks to her upcoming role as Tris Prior in the film adaptation of Veronica Roth’s wildly popular young adult novel, Divergent. And while this isn’t her first big role — she earned a Golden Globe nod starring opposite George Clooney in the Oscar-nominated film The Descendants – it’s her first major studio film in which she’ll play the lead. With Divergent landing in theaters in March, we have a feeling we’ll be seeing a lot more of Woodley, and we can’t wait. So in honor of what is sure to be a breakout year for the star, we’re taking a look back at her style evolution from newcomer to red carpet regular.
