Today Hereditary Prince Jacques and Princess Gabriella, the twins born to Sovereign Prince Albert II and Princess Charlène on 10 December, were christened in Monaco's Cathedral.
The children wore christening gowns from Dior and the godparents were Diane de Polignac Nigra and Christopher LeVine Jr for Prince Jacques and Gareth Wittstock and Nerine Pienaar for Princess Gabriella. Christopher LeVine Jr is the son of the only surviving child of Princess Grace's sister, Lizanne Kelly LeVine, and as such Prince Jacques's second cousin, while Diane de Polignac Nigra is a granddaughter of Thérèse de Polignac, who if I am not mistaken was a second cousin of Sovereign Prince Rainier III, making Prince Jacques's godmother his fourth cousin. Gareth Wittstock is Princess Charlène's brother, while I assume Nerine Pienaar is a friend of hers.
Princesses Caroline and Stéphanie attended with their families (the former as usual without her estranged husband), while the only foreign royals to have attended seem to have been Prince Charles and Princess Camilla of Bourbon-Two Sicilies, who are friends of the children's father.
