Well, this officially seals the deal: Blake Lively is a superstar. Sure, the actress already has hordes of adoring fans (including Vogue editor Anna Wintour and abs-olutely handsome hubby Ryan Reynolds), a Gucci fragrance campaign, a budding lifestyle brand and the ability to eat carbs without hitting the elliptical – but is she the face of a giant beauty brand? She is now! The former Gossip Girl star just signed on as L'Oréal Paris’s newest beauty ambassador, which means her impossibly shiny hair will be visible in ads starting in the new year. Blair is seething.
