Correct Answer: Shiloh Jolie-Pitt

Although they were born thousands of miles apart, Kingston Rossdale and Shiloh Jolie-Pitt were born the same weekend in 2006. (Kingston arrived on May 26 at Cedars-Sinai Medical Center in Los Angeles; Shiloh made her debut at Cottage Medi-Clinic in the African nation of Namibia on May 27). A few months later, the wee ones had a play date when the Rossdales visited the Jolie-Pitts' Santa Barbara, Calif., home.
