Princess Caroline of Monaco on holiday with her husband Prince Ernst August of Hanover, their daughter, Alexandra (b. 2000) and Caroline's son Andrea Casiraghi (b. 1984).
Monegasque royal Princess Caroline of Monaco has been spotted making the best of the summer sun, cruising the waters of the Mediterranean on board her luxury yacht.
Speculation is growing that Princess Caroline of Monaco is set to split from her German husband after he was allegedly photographed kissing another woman in Thailand.
Princess Caroline, 52, spent Christmas in the Swiss ski resort of Crans-Montana while her husband Prince Ernst August of Hanover was in Phuket.
The German celebrity magazine Bunte published photographs of the prince with another woman today.
That triggered other reports in the German media on long-standing rumours of a divorce later this year.
A divorce could be one of the most costly in history. The prince has a wealth estimated at more than £5billion in property, estates and investments and under German and French law Princess Caroline would be entitled to half.
'Betrayed!' said the Hamburger Abendblatt newspaper. 'Poor Caroline. What does this scandal mean for Monaco?' said the country's biggest selling newspaper Bild.
And Bunte, which has in the past had a direct line into royal houses of Hanover and Grimaldi, said: 'The First Lady of Monaco simply cannot accept being publicly duped in such a manner by her marriage partner.'
The pictures were taken on Phuket's Freedom Beach and show the prince - who is a distant cousin of Queen Elizabeth II - in the sea with the woman, who bears an uncanny resemblance to his long-suffering spouse.
Separate lives: Princess Caroline of Monaco has not been seen with her husband Prince Ernst of Hanover since early June
Princess Caroline of Monaco was said to be about to divorce - leading to claims that a 700-year-old curse on her family had struck again.
Reports in France say that the third marriage of Grace Kelly's eldest daughter is all but over. The 52-year-old is living a separate life from her husband Prince Ernst of Hanover, 55.
'It looks like the end,' said a source at French magazine Point de Vue, which specialises in European royal families.
'Both Caroline and Ernst have been at the centre of scandals in the past, but this really is breaking their hearts.'
The split after ten years of marriage is the latest to afflict the Grimaldis, the name of Monaco's royal family.
Local superstition says a 13th century witch cursed them, warning none would have a long or successful marriage.
Caroline, who has not been seen with Ernst since early June, has left the family chateau in Fountainbleau, south of Paris, to return to Monaco. She divorced her first husband and her second died in a boating accident.
Her sister Stephanie married a bodyguard, whom she divorced before marrying and divorcing a circus acrobat.
Caroline's mother, Princess Grace - former film star Miss Kelly - was killed in a car crash, leaving her devoted husband, the late Prince Rainier III, distraught.
