Kristen Stewart

Though a superstar presence in recent years thanks to a certain insanely popular vampire series, Kristen Stewart has actually been working since she was eight years old, after an agent saw her perform in her elementary school's Christmas play. She played the daughter of Jodie Foster, Patricia Clarkson, and Sharon Stone before landing her first leading role in the family-friendly action-comedy Catch that Kid. Ever since, there's been no looking back, and Stewart has become one of the most popular leading ladies of her generation.
