Now she and Billy have one of their own. On March 12, Jolie, 26, and Thornton, 46, announced that they had adopted a 7½-month-old Cambodian baby whom they named Maddox. Jolie first visited Cambodia while filming 2001's Lara Croft: Tomb Raider
and returned last summer with the U.N., for whom she now serves as a goodwill ambassador. "Last November," the couple said in a statement, "we visited an orphanage in Cambodia and met a little boy we felt a connection to and that we wanted to be our son."
While the pair awaited the usual approvals, the U.S. government halted adoptions from Cambodia amid allegations of baby selling. Only when the ban was lifted for dozens of families earlier this month did Jolie and Thornton take custody of Maddox in Africa, where Jolie is filming the upcoming movie Beyond Borders
