It is easy to forget that when King Charles and Camilla married, Princes William and Harry got not just a new step-mum, but a new step-brother and step-sister as well.
The Queen Consort already had a family of her own when she said 'I do' and joined the Royal Family, including two children with her first husband Andrew.
Laura Lopes and Tom Parker Bowles made their first public appearance at their mum's wedding in 2005 and sat for the official photos.
They very much prefer to take a backseat, but will also happily be there by her side at the big events.
Tom has the curious honour of having the King as both a stepfather and a godfather.
And they will soon have a Queen mother following Tuesday's announcement.
King Charles' Coronation is just four weeks away and the official royal invitation shows that Camilla's title is about to change, seven months after the death of the Queen.
The official coronation invitation, designed by Andrew Jamieson, a heraldic artist and manuscript illuminator, names King Charles III and Queen Camilla.
Despite shunning the spotlight, both Laura and Tom are expected to attend and they will have important jobs as their children will take on starring roles.
Gus, Louis and Freddy will Camilla's Pages of Honour, along with her great-nephew, Arthur Elliot.
Laura and Tom attended William's wedding to Kate, Princess of Wales, with Laura's daughter acting as a bridesmaid, and both siblings were also there to watch Harry marry Meghan, Duchess of Sussex.
It has been a traumatic few years for her eldest child, whose girlfriend tragically died of cancer at the age of 42 after her diagnosis was reportedly delayed by lockdown.
Journalist Alice Procope died at home on March 17 2021 as they planned their future after two years together.
Tom is primarily known for being a successful food writer and has a number of cookbooks. He's also worked as the Mail on Sunday's food critic.
Over the years he has also been a judge on TV cookery shows
Laura was educated at a Catholic girls boarding school in Dorset, and then studied History of Art and Marketing at Oxford Brookes University.
She leads a private life, but used to be more of a mover and shaker. Before settling down, Laura worked as Tatler’s motoring correspondent.
She then moved into the art world, first managing The Space Gallery in London, and then co-founding London's Eleven Gallery in 2005, where she was also director.
Laura married chartered accountant Harry Lopes in Wiltshire in 2006. He went to Eton College and spent some time underwear modelling for Calvin Klein.
Harry is the son of a baron and is in line to inherit Gnaton Hall in Devon, as well as the Skelpick estate in the Scottish Highlands.
While Camilla has been given her official title through marriage, there's nothing to suggest her children and grandchildren will be offered royal titles or duties.
“Even though their mother Camilla is now the Queen Consort, Tom and Laura are still not going to have a formal role within the Crown as they are not of the blood," Thomas Mace-Archer-Mills, founder of the British Monarchists Society, told iNews.
