Leighton Meester headed out to Madrid, Spain to help launch the new line of hair cosmetics for Herbal Essences, for which she is the new spokesmodel. She really did look gorgeous in her Hervé Léger dress and Pierre Hardy sandals, and I am loving her new blond hair too. Did you know she is actually a natural blond? After seeing her as Blair Waldorf for so long now, I never could have pictured her as a blond. Either way she is beautiful.
