Prince Harry and Meghan Markle may look set to give Trooping the Colour this year a miss - but they used to be regulars at the event.
Meghan made her debut at the monarch's birthday parade after marrying Harry in 2018 and a year later, after becoming mum to Prince Archie, she made her second appearance.
That year, she rode in a carriage with Harry, Queen Camilla and the Princess of Wales and wore a chic navy outfit.
But it wasn't her clothes that caught the attention of eagle-eyed royal fans - it was her jewellery, specifically her engagement ring.
When Harry proposed back in 2017, he designed a gorgeous ring made with two diamonds from his mum Princess Diana's collection and one from Botswana, on a plain gold band.
But by June 2019, Meghan was wearing the ring on a thinner micropave band - along with another stunning ring.
And in a book about the couple, it was explained why the ring was changed - and the meaning behind the eternity band.
In their biography Finding Freedom, royal reporters Omid Scobie and Carolyn Durand write: "On May 19, 2019, Harry also surprised his wife of one year with the gift of a ring that he had created with jeweller-to-the-stars Lorraine Schwartz, a favourite of Meghan's.
"The conflict-free diamond eternity band paid homage to the family of three with Meghan's, Archie's and Harry's birthstones (peridot, emerald, and sapphire, respectively) on the underside of the ring."
The jeweller told the authors: "Harry wanted to make it special. He's the loveliest person ever. So romantic, so thoughtful."
The book continues: "Harry also thought to have Lorraine resize and reset Meghan's engagement ring with a new diamond band."
The first King's birthday parade of Charles' reign is due to take place tomorrow with a huge turnout of royals set to appear.
It will see 1,400 soldiers, 200 horses and 400 musicians, as well as members of the Royal Family who will ride on horseback and in carriages process from Buckingham Palace and down the Mall to Horse Guard’s Parade.
After a military service there, the royals will head back to the palace and watch a huge RAF flypast from the balcony.
Harry and Meghan attended the late Queen's final Trooping the Colour last year - although were not permitted to appear on the balcony as it was limited to working royals only.
And this year, they are not expected to attend at all - despite it being the first poignant ceremony for Harry's father Charles.
