Unseen footage of the Duchess of Cambridge reveals how she fled to Dublin with her mother Carole to lick her wounds during her breakup in 2007 with Prince William.
The duke and the duchess are the epitome of a solid royal marriage, but more than a decade ago they were briefly divided at the end of March 2007.
Before the news of her break up reached the newspapers, Kate had already flown to Ireland with her mother and now invisible images, discovered by The Irish Independent, show how she put on a brave face while mixing in her friend's art exhibition Gemma Billington.
Even at 25, Kate wore an elegant style in a black jacket with polka dots and skirt suits, and smiled when she met the former Arsenal and Manchester City player Niall Quinn and members of the pop group The Thrills.
After enjoying the paintings and mingling in the champagne reception, Kate and Carole completed a cultural day with a tour of the National Gallery of Ireland.

Kate, 25, was nursing a broken heart, but she managed to put her problems aside while chatting animatedly with Ben Carrigan, of the Irish pop group The Thrills.
Kate and William separated for a few months after he gave an ultimatum to royalty to be proposed.
By then, they had been dating for five years since their meeting at St. Andrews University and Kate was ready to think about settling down.
But the prince was beginning a new chapter as an army officer with the Blues and Royals and was eager to avoid the mistake his parents had made by marrying too hastily.
William decided to celebrate the end of their relationship quite differently: with a trip to the Mahiki club in central London. The news of his division was not yet public, but those around him had more than an idea of what was happening when he jumped on a table screaming "I'm free!"

Then he slipped into his version of the robot dance, famous for the English footballer Peter Crouch, and suggested to his friends to drink the menu.
The news of his division broke in public the next day.
In mid-May, the couple spoke by phone, in June Kate was seen at a costume party in William's barracks,
In August, the couple traveled by plane to spend a vacation in the Seychelles, where William made a promise that a proposal would be presented in the future.
The couple got engaged in October 2010 and got married in April of the following year.
During an interview to mark their commitment in November 2010, both admitted that the brief time of separation had been the best.
"I think at that time I was not very happy with that, but in reality it made me a stronger person, you discover things about yourself that maybe you did not realize," he said.
"I think you can get quite consumed by a relationship when you're younger." I really valued that time for myself too, though I did not think at the time!
William added: "We were both very young … we both found ourselves and we are different characters.
"We tried to find our way and we were growing, so it was just a bit of space and it worked for the better."
Prince William and Kate arrived to pose for photographs at the State Apartments of St James Palace to commemorate the announcement of their commitment in 2010. In an interview, both admitted that their brief division had improved their relationship for the better.
