In the beauty realm, Victoria Beckham may be best known for that iconic asymmetrical bob, a style she's worn in a variety of shapes and hair colors over the years. The pop-star-turned-fashion-designer has reinvented her look many times since her days as Posh Spice of Spice Girls fame, however. And while her structured clothing aesthetic has stayed pretty consistent, Victoria definitely knows how to have fun with her famous coifs. Not only has she tried jet black and even platinum blond strands, but she's even sported a pert pixie. In honor of Victoria's 40th birthday today, see all her best styles when you scroll through.
