The Prince and Princess of Wales are making a rare joint appearance alongside King Charles and Queen Camilla today during a special royal ceremony in Edinburgh.
William and Kate will be among the guests at a service of thanksgiving and dedication at St Giles' Cathedral in the Capital to honour the Coronation of the new monarch.
Charles will be presented with the Honours of Scotland which are the oldest crown jewels in Britain after a special procession from the Palace of Holyroodhouse.
However, looking at the order of the service for the ceremony may lead to confusion for some as to why the Prince and Princess of Wales don't seem to feature in it, the Mirror reports.
The reason being because William and Kate actually have more than one royal title with the pair inheriting a series of new ones following King Charles' accession to the throne last year.
This being said, many of their new titles are not very well known including their Scottish titles -Duke and Duchess of Rothesay.
The title Duke of Rothesay is always reserved for the heir to the throne along with the other Scottish styles - Baron of Renfrew, Lord of the Isles, Earl of Carrick and Prince and Great Steward of Scotland.
This means the future King's wife Kate Middleton is also known as Baron of Renfrew, Lady of the Isles and Countess of Carrick.
However, William and Kate will mainly go by Duke and Duchess of Rothesay in Scotland as this title is higher in rank.
Today's historical ceremony in Edinburgh is part of the annual Royal Week in Scotland and will kickstart with a people's procession of around 100 community groups who 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 separate royal procession will travel from the Palace of Holyroodhouse to the cathedral with the public being able to watch both processions from the Royal Mile.
A 21-gun salute will fire from Edinburgh Castle to mark the end of the St Giles' service before the royal procession travels back to the palace.
The Stone of Destiny will also be in the cathedral during the service and there will also be a magnificent RAF flypast finale by the Red Arrows to conclude the event.
The people's procession will include representatives from a wide range of organisations and charities in Scotland including Guide Dogs, the Scottish Youth Parliament, the Scottish Tartans Authority, Scouts and Girl Guides and the College of Master Kilt Makers.
