She may be known by her grandest title of Princess of Wales - but it's not Kate's only royal style.
Both she and Prince William inherited a raft of new titles on the accession of King Charles last year - with many of them little known.
They include the Duke and Duchess of Cornwall, which are the titles they will use when in the county, and another style they'll be able to use on an exciting upcoming trip next month.
It was announced by Buckingham Palace that William and Kate will take part in engagements alongside Charles and Queen Camilla in Scotland in July to mark the Coronation.
And while they are in Scotland, William and Kate will be able to use their new Scottish titles - the Duke and Duchess of Rothesay.
That title Duke of Rothesay is always reserved for the heir to the throne along with the other Scottish styles - Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland.
This means the heir's wife Kate is also known as Countess of Carrick, Baroness of Renfrew and Lady of the Isles.
However, William and Kate will use Duke and Duchess of Rothesay - as this title is higher in rank.
While in Scotland next month, they will attend an event on July 5, where King Charles will be presented with the Honours of Scotland – the oldest crown jewels in Britain – at a national service of thanksgiving at St Giles’ Cathedral in Edinburgh as part of Royal Week.
A people’s procession of around 100 community groups will collect the honours from Edinburgh Castle.
The procession will be escorted to the cathedral by the Royal Regiment of Scotland and its Shetland pony mascot Corporal Cruachan IV, supported by cadet musicians from the combined cadet force pipes and drums.
Meanwhile, a royal procession will travel from the Palace of Holyroodhouse to the cathedral, with the public lining the Royal Mile to view both processions.
A 21-gun salute will fire from Edinburgh Castle at the end of the St Giles’ service before the royal procession travels back to the palace.
The Stone of Destiny will be in the cathedral during the service, and there will also be a fly-past by the Red Arrows following the event.
The people’s procession will include representatives from a wide range of organisations in Scotland, including the Scottish Youth Parliament, Guide Dogs, the Scottish Tartans Authority, the College of Master Kilt Makers, Scouts and Girl Guides.
