Happy 31st Birthday, Emily Blunt! Named one of People’s Most Beautiful Women in 2013, the fashion-forward star graced InStyle’s May 2013 issue (where she rocked an edgy berry-colored Burberry Prorsum dress) and spoke about her fearlessness when it comes to fashion. “I like to mix it up and be a bit more courageous,” she told the magazine. “I don’t feel I have any particular style. I’m willing to experiment.” Emily—who’s been married to actor John Krasinski since 2010—was especially radiant during her pregnancy with her daughter Hazel, who they recently welcomed just this month.

Besides juggling life as a new mom, Emily will co-star with Tom Cruise in the sci-fi film Edge of Tomorrow (due out in June) and will reunite with her Devil Wears Prada co-star Meryl Streep in the screen adaptation of the musical Into the Woods, which also stars Johnny Depp, Chris Pine and Anna Kendrick (set for a Christmas 2014 release). To celebrate Emily’s birthday, see some of her most stylish looks in our gallery.
