Brad and Angelina to marry © Reuters/Lucas Jackson After seven years and six children together, Brad Pitt and Angelina Jolie finally look set to marry. It has been confirmed that the celebrity couple are engaged, after Jolie was photographed in Los Angeles wearing a large diamond ring, designed by Pitt. A spokeswoman for Pitt said: "Yes, it's confirmed. It is a promise for the future and their kids are very happy. There's no date set at this time. Jewellery maker Robert Procop said he had created Jolie's engagement ring in collaboration with her now fiancee and had been working on it for a year. A spokeswoman said: "The full creative journey - from conception to completion - took a year, with Brad Pitt waiting until the perfect moment to unveil this special jewel to Angelina Jolie." Pitt, who is 48 and Jolie, 36, are raising six children together, including three adopted kids, all under the age of 11. He said earlier this year that pressure from their children was finally forcing them to consider getting married. He had previously dismissed the idea as unnecessary and said they were waiting until gays and lesbians could legally wed.
