The Duke and Duchess of Cambridge were all smiles yesterday as they joined the 1st Battalion Irish Guards for their annual St. Patrick’s Day parade at Mons Barracks in Aldershot, England.

The Duchess also presented the regimental mascot Domhnall, an Irish Wolfhound, with his very own shamrock.

She also wore the Queen Mother’s golden shamrock brooch – one that the Queen Mother wore every year when she was the one handing out shamrocks!
