Now 2013 is set to follow suit as not one but two Monegasque royals are to walk up the aisle later this year.
Charlotte Casiraghi, 27, and her brother Andrea, 29, will both wed later this year, watched by their mother, Princess Caroline of Hanover, uncle, Prince Albert, and royals from around the world.

His wife to be is the socialite daughter of Colombian businessman Julio Mario Santo Domingo, Jr. and Brazilian socialite Vera Rechulski and the pair already have a son, Sacha, who was born in March this year.
Fashion designer Tatiana is supremely well connected, and is best friends with Margherita and Teresa Missoni, who have also had input into the heiress' fledgling fashion line, Muzungu Sisters.
Other friends include supermodel Natalia Vodianova and Chanel model and Karl Lagerfeld favourite, Alice Dellal.
The wedding itself has been described as a 'private' affair by a spokesman for the couple, although if Tatiana follows the example of her sister Lauren, a glimpse inside the wedding could come via the pages of Vogue.

Charlotte, who is expecting her first child at the end of the year, has created a successful career as a showjumper for herself and also appeared in Gucci's 'Forever Now' campaign.
Blessed with her grandmother Grace Kelly's film star looks, Charlotte has appeared on the cover of French Vogue and writes several fashion titles including AnOther Magazine and the Independent's Sunday supplement.
Although Charlotte usually plumps for Chanel couture when attending events, she also loves Giambattista Valli and is friends with Stella McCartney.
So will the dress be Chanel or Stella? You'll have to wait until autumn to find out!
