I'm told Camilla recently gave a braided leather necklace to Joe to match her new gold Panthera ring.
But this isn't some sort of promise ring kind of thing.
You see, Camilla is the new celebrity spokesperson for H.E.L.P., an organization dedicated to bettering children's lives in Malawi.
Sales of Joe's necklace and Camilla's ring—both are from jewelry designer Lori Leavitt's Panthera Collection—benefit H.E.L.P. Leavitt's line also includes bracelets, cuff links and keychains. Prices rage from $298 to $2,050.
Joe and Camilla were recently spotted wearing their new pieces during a lunch stop to Cafe du Village in the Hancock Park neighborhood of Los Angeles.
The Push and 10,000 B.C. actress will also appear in a new print advertising campaign with the tagline, "What Love Means."
She also plans to visit Malawi this summer for about 10 days. "She's going to be totally hands on," a source says. "She's going to be doing things like helping build schools."
While I'm told Belle's mom will be on the trip, no word if Joe will be joining them.
