"Angelina adopted a Cambodian baby. I'm a grandfather today," he told reporters.
Jolie, 26, met Thornton, 46, while working on the set of the 1999 comedy Pushing Tin, and the two eloped in Las Vegas a year later. Thornton, 46, has two children from a previous marriage. The two, known for publicly behaving like a honeymoon couple on drugs, have mentioned the possibility of adopting before.
Last summer, Jolie was named Goodwill Ambassador by the United Nations High Commission for Refugees (UNHCR) and undertook a mission on behalf of the United States for UNHCR to Cambodia soon after. She also traveled to Pakistan and to Africa.
She is currently in Africa working on Beyond Borders, a film about a medical student who thinks he has found his calling as an international disaster relief worker--until he gets sidetracked by a well-heeled socialite involved in a troubled marriage. It is slated for release some time this fall.
In fact, Oscars seems to run in the family. Thornton received an Oscar for best screenplay based on material previously produced or published for Sling Blade in 1998 while Jolie won an Oscar in 2000 for best supporting actress for her role in Girl, Interrupted.
