Angelina Jolie became the poster mommy for international adoption, traveling the world to rescue babies in need of a good home. Son Maddox, now 8, was first, adopted from Cambodia in 2002. After partner Brad Pitt signed on as dad, the couple added Ethiopian daughter Zahara, now 5, and their biological daughter Shiloh, now 3. In early 2007, the Jolie-Pitt clan grew again, this time with 3-year-old Pax from Vietnam, who became big brother to Jolie and Pitt's biological twins, now-1-year-old Knox and Vivienne. "They're the greatest little people I've ever met, and they give me so much joy," Jolie has said about their adopted kids.
