Angelina Jolie has filed papers to adopt a child in Vietnam, the country’s top adoption official said Friday.

According to the Associated Press, the director of Vietnam’s International Adoption Agency said an American adoption agency representing Jolie had submitted the paperwork.

“She just filed the papers this week,” Vu Duc Long said.

Jolie, 31, and Brad Pitt, 43, are already parents to son Maddox, 5, and daughters Zahara, 2, and Shiloh, 9 months.

Jolie said in December that she wanted more kids. “I’d like to add many more children and many more obstacles and many more things to my life,” she told reporters while promoting her movie The Good Shepherd.

And Pitt said in January that he and Jolie were hoping to expand their family. “Always, of course,” he said. “We’ll let you know when we get there.”

The globe-trotting couple spent Thanksgiving in Vietnam, taking a self-guided tour of Ho Chi Minh City, dining at a popular local restaurant converted from an old temple and later cruising around the former Saigon on a motorcycle.

Asked by a local newspaper how he felt about traveling the busy streets, Pitt replied, “There will be no problem,” adding, “We had a wonderful day in Vietnam.”

Jolie traveled to Vietnam again in January for a meeting about the Maddox Jolie-Pitt Project, her charity aiding her son’s native country of Cambodia.
