The Duke of Cambridge and his wife Duchess Catherine went to the regiment's barracks in Aldershot, Hampshire, South East England, to attend the troops' annual St. Patrick's Day Parade.

After the couple watched the two hundred soldiers from the First Battalion Irish Guards marching on the Parade Square and Catherine upheld the 144-year-old royal tradition of presenting shamrocks to the officers and guardsmen, they then met with the soldiers, other guests and families.

Army wife Susan Crittenden - who lives at a nearby barracks - got to meet the prince and showed him a photo of her with his dad Charles when she was introduced to him during a visit to Caterham barracks 13 years ago.

In the picture, Susan, 49, is shown holding her then-two-year-old son Reece - who is now 15 - and revealed the heir-to-the-throne had given her a kiss on the cheek and when she asked William if he would do the same, the royal heartthrob was more than happy to oblige.

According to reports, she said: "I told him I had a kiss from Prince Charles and he said, 'My goodness.' And when I asked him for a kiss I got one. He was very charming."

Catherine - who is eight months pregnant with the couple's second child, a sibling for Prince George - met with several young cadets and told them she was delighted to see so many girls and women involved.

During the meet-and-greet, William, 32, enjoyed a pint of Guinness to mark the celebration of the patron saint of Ireland, while his wife opted for just a glass of water.
