Happy birthday, Rosie! The gorgeous English model turns 25 today, and she has plenty of reasons to celebrate. Rosie was a relative unknown until 2008, when she scored her big break by way of the opportunity of a lifetime: Burberry's chief creative director, Christopher Bailey, chose the Victoria's Secret catalogue model to replace Agyness Deyn in the British fashion house's fall/winter ad campaign. It was all uphill from then on, with a British Vogue cover following shortly thereafter. Now Rosie is practically a household name, nearly as ubiquitous a model as her VS Angel counterparts Alessandra Ambrosio or Adriana Lima, and it shouldn't take any more than a look at her to fathom what makes her a star (here's a hint: it's not "Transformers"). Her intimidating beauty and leggy stature is offset by a quiet British modesty and sense of propriety, not to mention a standout dress sense. Rosie doesn't do it all on her own, so let's give credit where credit is due — Cher Coulter, the stylist also behind Kate Bosworth, Elizabeth Olsen, and Sienna Miller, to name a few, is the one responsible for Rosie's elegant, casual, always impeccable look. Yeah, I want Cher to be my stylist, too!
