Monaco: Prince Albert II of Monaco and Princess Charlene married in a religious ceremony in their palace on Saturday, one day after their civil wedding, finalising their union in front of 800 guests.

The couple each said "oui" -- he first followed by her-- in the courtyard of the Grimaldi dynasty's home overlooking the Mediterranean to the ritual questions posed by Archbishop of Monaco Bernard Barsi.

The archbishop held the couple's hands together anddeclared: "What God has joined together, let no man put asunder, then blessed their relationship."

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 exchange and the congregation prayed.
