Some 2000s It Girls weren’t made during the 2000s. They were forged in the 1990s and just kept going. Mary-Kate and Ashley Olsen made their TV debut at NINE MONTHS old, sharing the role of Michelle Tanner on Full House. By age six, they had a production company. By age 10, they were a billion-dollar direct-to-video empire. By the time they were teenagers, they were running a global merchandising operation that included clothing, perfume, books, magazines, and dolls. They were the original child-star moguls with an endless twin movie wrap sheet: Getting There, Holiday in the Sun, It Takes Two, Passport to Paris, Our Lips Are Sealed, New York Minute… you get the point. And then they did something nobody expected. Photo: Getty Images
