Angelina Jolie Wedding Ring: 'No, It's Not'

Angelina Jolie has squashed rumors of a secret wedding after she was photographed several times wearing a gold band in place of her engagement ring,

The actress is engaged to Brad Pitt, with whom she shares six children. The pair has been together since 2005 and announced the engagement in April last year, but have not revealed any wedding plans.

Along her trip from Los Angeles to Africa's eastern Congo this week, Jolie has sparked speculation that she and Pitt had already married with the gold band worn on her wedding finger.

When asked if the ring was in fact a wedding ring, Jolie replied, "No, it's not," according to TMZ.

Meanwhile, Jolie is a special envoy for the U.N. refugee agency. The 37-year-old actress traveled to the Nzulo camp near Goma along with British Foreign Secretary William Hague over the weekend, and will visit the area's female natives, according to the Associated Press.

"I wake up in the morning as a mom, and I turn on the news like everybody else, and I see what's happening," Jolie said to OMG! Yahoo News. "I want to be a part of the world in a positive way."

Known for her humanitarian efforts, Jolie's visit to the Democratic Republic of the Congo as well as Rwanda will raise awareness about the presence of sexual violence in war zones.

Rebel groups as well as Congolese soldiers that operate in eastern Congo commonly use sexual violence as a weapon of war. The International Rescue Committee said it has provided care for over 2,500 women and girls who have been raped or abused over the last year alone, reported the Associated Press.

As part of an effort to prevent sexual abuse, the IRC distributes kits complete with flashlights and whistles in addition to cleansers so that women can avoid bathing in creeks where sexual attacks often occur.

Jolie laid wreaths at the Gisozi genocide memorial in the Rwandan capital of Kigali wearing all black Sunday. The ceremony honored the estimated 800,000 victims that died during the country's 1994 violence between the Hutu and Tutsi tribes.
