This baby-faced actress first turned heads as a cast member of The Real World: London. A professional model from the age of 14, the native Australian quickly earned the name "Ms. Mischief" among her housemates, pulling outlandish stunts like streaking through their London neighborhood and prank calling strangers. Post-Real World, Jacinda went on to a successful acting career. You can see her in high-profile films like The Human Stain, Bridget Jones: The Edge of Reason, The Namesake, and New York, I Love You. In 2004, Jacinda married actor Gabriel Macht and gave birth to their first child, Satine, in 2007.
