Mira Sorvino contains multitudes: She's a Harvard grad, an Oscar winner, a U.N. ambassador, a onetime muse of the late Giorgio Armani and a protective mom of four. (She and her husband of 21 years, Christopher Backus, are parents to Mattea, 20, Johnny, 19, Holden, 16, and Lucia, 13.) We're only half-kidding when we ask: Has her hair color put her on top? Known for iconically blond roles in Romy and Michele's High School Reunion, Norma Jean & Marilyn and Mighty Aphrodite, she is actually a natural brunette.
