The couple each said "oui" in the courtyard of the Grimaldi dynasty's home overlooking the Mediterranean, at a service led by the Archbishop of Monaco Bernard Barsi, who blessed their relationship.
The archbishop held the couple's hands together and declared: "What God has joined, men must not divide."
Then, in front of witnesses, the couple -- Charlene, noticeably less tense than she had been at the first ceremony, and occasionally smiling -- exchanged 18 carat rings in white gold and platinum by the House of Cartier.
A South African singer celebrated with a popular, upbeat wedding song from Charlene's homeland: "Diviner of the roadways, the knock knock beetle / It just passed by here, the knock knock beetle."
The smiling couple shared a brief and the congregation prayed.
