The couple, who raise six kids together, got engaged recently and it is said that they will tie the knot this weekend, reported Sun Online.
The former boss of British jewellers Asprey & Garrard has been busy producing matching bands for them at the Grand Hotel du Cap Ferrat, in the south of France.
"Robert's been busy all year making Brad and Angie's wedding rings. They are matching rose gold bands with a tablet-cut diamond in them and their vows to each other engraved in them. You can't see it with the naked eye but they both know they're there," a source said.
According to Michael Latz, who is mayor of the village of Correns near Pitt and Jolie's home, the couple have booked a church nearby for the ceremony.
