United Nations' goodwill ambassador Angelina Jolie was joined by actor Brad Pitt for private briefings about refugee situations around the world, a spokeswoman at the U.N. refugee agency said Wednesday.

"He seemed very interested in our work," said Jennifer Pagonis at the U.N. High Commissioner for Refugees.

Pitt, divorced from actress Jennifer Aniston earlier this year after 4 1/2 years of marriage, has been romantically linked to Jolie for months.

It was the first time that Pitt has joined Jolie on a visit to UNHCR when the two met with UNHCR staff on Tuesday at the agency's Geneva headquarters, Pagonis said.

She refused to comment on where Jolie — or the pair — might be headed, because the agency does not disclose ahead of time the dates or locations of its ambassadors' missions.

"It's for her own security and the security of the refugees," Pagonis said. "That's the only way she can have direct contact with people and hear their stories."

Jolie, who has made some 30 missions for the agency since becoming goodwill ambassador in 2001, went to Pakistan in May on her last UNHCR trip, well before the devastating Oct. 8 South Asia earthquake, according to the agency's Web site.

Jolie — who won a supporting-actress Oscar for 1999's "Girl, Interrupted" — earlier this month accepted the Global Humanitarian Award for her refugee work.
