Legend has it that the reigning family of Monaco will never find true happiness in marriage.

This 13th century ‘curse’ was laid upon them by a girl who was allegedly raped by Prince Rainier I. She became a witch in order to exact her revenge upon him and his family – the Grimaldis – who seem to be genuinely affected.

This time around it’s Princess Caroline – again – with reports that she is splitting from husband number 3, Prince Ernst August of Hanover.

Caroline, who has not been seen with Ernst since early June, has left the family chateau in Fountainbleau, according to magazine Point de Vue.

Below, some of the other nuptials gone wrong in the house of Grimaldi:

- Prince Rainier III, who died in 2005, lost his wife Grace in 1982 when she perished in a car accident. It was even reported that their marriage had gone sour long before the tragedy.

- Princess Stephanie married her bodyguard, had two children with him, and then divorced him when he was photographed cheating on her with a model. She had another relationship that went nowhere with another bodyguard, but it did result in a third child – daughter Camille. Stephanie has had a string of boyfriends since, one which culminated in another brief marriage.

- Prince Albert, the current reigning prince of Monaco, has fathered children with two different women and has dated many models and actresses, but has never settled down. His current girlfriend, Charlene Wittstock, is rumored to be the next reigning princess but so far no engagement ring has appeared.

- Princess Caroline married playboy Phillipe Junot against her parents’ wishes. She was only 19 at the time, and two years after they wed, they were divorced. Caroline tried to have the marriage annulled, but the Catholic church refused her.

Caroline met and married Stefano Casiraghi a couple of years later. The world thought that the princess had finally found happiness with a soulmate, but Casiraghi died in a speedboat accident at the age of 30. He left Caroline with their three children.

The princess married again, this time to a descendant of King George III of the United Kingdom. Prince Ernst of Hanover seemed to be a bit too gauche but she married him anyway after it was discovered she was pregnant with their daughter Alexandra.

 Princess Anne’s son Peter Phillips and his Canadian fiancée Autumn Kelly have lifted the lid on their very private, four-and-half-year relationship by giving the first interview ahead of their May 17 wedding to HELLO! magazine.

Many happy congratulations to Peter Phillips upon his engagement. He is set to wed Autumn Kelly, native of Canada. Peter is the son of HRH Princess Anne and nephew of HRH The Prince of Wales.

Funny that I just mentioned Peter in this previous post as a candidate to represent monarchy in Canada. Now he’s marrying a Canadian. :) Wonderful news!
