"I've never done anything like this," says Kristen Stewart in this behind-the-scenes video from her Balenciaga shoot with Steven Meisel. And this isn't just PR talk — the brand's Florabotanica fragrance is Stewart's first major campaign. "It's an odd relationship that us actresses get to have with fashion," she explains. But that oddness may be exactly what attracted Balenciaga designer Nicolas Ghesquiere's attention. See both Stewart and Ghesquiere talk about the project in this exclusive video.
