There she is!

A week after she and Brad Pitt announced their long-awaited engagement Angelina Jolie popped up in Ecuador over the weekend. Although Jolie, Pitt and their six kids had been celebrating the nuptial news with an extended stay at the nearby Galapagos Islands, the 36-year-old star was solo -- and makeup free! -- meeting with Colombian refugees in Ecuador.

Walking through the rainforest in rubber boots, tank tops and backpack, the In the Land of Blood and Honey director also met with farmers in the region and Antonio Guterres, a High Commissioner for Refugees; Jolie herself was promoted to special envoy to the UNHCR (United Nations High Commissioner for Refugees) last week after over a decade of serving as a goodwill ambassador. She's set to work at the diplomatic level on behalf of the UNHCR.

In photos from the visit, it appears that Jolie left behind her enormous, $500,000 engagement ring (which Pitt helped design with Robert Procop) for her humanitarian visit.

Last week, Jolie, Pitt, 48, and their brood -- Maddox, 10, Pax, 8, Zahara, 7, Shiloh, 5, and twins Vivienne and Knox, 3 -- arrived at an exclusive, ultra-private resort on Santa Cruz Island in the Galapagos Islands, renowned worldwide as the ultimate destination for wildlife lovers and eco-tourists.

All six kids were present when Pitt proposed earlier this spring.

"Everyone hugged once she put [the ring] on," an insider told Us. "She went around and showed it to each of the kids."
