Princess Charlotte curtsies to the new King Charles and nearly loses her footing - watch.
Princess Charlotte has been curtseying ever since she was 2 years old, when her family took a tour of Poland and Germany and she gave a little curtsey to the Polish dignitaries.
Princess Charlotte is a master of royal curtsies — but she almost lost her balance at the Coronation Concert. The daughter of Prince William, 40, and Kate Middleton, 41, slightly stumbled when she curtsied to King Charles and Queen Camilla as they entered the royal box to watch the royal concert on Sunday.
Since Charles has taken to the throne, the tradition has changed so that now, in the Royal order, Camilla has outranked Princess Anne - meaning all the royal women in the family must (and will) curtsy to her.
Prince William defied royal protocol at the King's Coronation when he chose not to bow to Queen Camilla at the Coronation Concert. A body language expert claims that the Prince of Wales might have found it strange to perform such a gesture to his stepmother.
At public engagements, it's not uncommon see royals greet each other with a bow or a curtsy. These greetings, however, often depend on a royal's rank. All royals are expected to bow or curtsy to the sovereign and his wife, King Charles and Queen Camilla.
William Technically Has to Bow to Queen Camilla
Sources tell Page Six that everyone in the royal family is expected to bow to Camilla now that she's Queen (well, Queen Consort, technically).
The former Duchess of Cambridge was expected to curtsy to Anne, Beatrice, and Eugenie, but not if she was with Prince William. But, even when Kate was with William, she still had to curtsy to Anne. The Princess Royal's rank did not change.
Although Camilla outranks Kate as a "Majesty" compared to her "HRH" status, the princess' firstborn son, Prince George, will one day inherit the throne, which is not something the current Queen can claim.
There's a pretty straightforward reason as to why: Twenty years ago, Prince Edward, Duke of Kent, decided that players no longer needed to curtsy or bow to royals that weren't the sovereign or the heir to the throne.
George's Chapel went by. When King Charles and Queen Camilla walked by in their royal regalia — blue mantles (robes) and hats topped with ostrich feathers — Kate dipped into a curtsy, expertly keeping her balance as she placed one foot behind the other and knelt down.
The Princess of Wales paid respect to King Charles' wife
During the coronation concert at Windsor Castle, Princess Kate curtseyed as Queen Camilla passed her on her way to her seat, with the act an age-old sign of deep respect when greeting a monarch.
So Catherine must curtsey to Queen Camilla, and if William is not present she must also curtsey to her cousins-in-law Beatrice and Eugenie, and her aunt-in-law, the Princess Royal.
And when it comes to fashion, she is most often spotted wearing a dress - but why does she always wear them? The Princess of Wales supposedly likes her children to wear outfits that are as timeless as possible.
So Catherine must curtsey to Queen Camilla, and if William is not present she must also curtsey to her cousins-in-law Beatrice and Eugenie, and her aunt-in-law, the Princess Royal. The Princess of Wales was snapped curtseying on camera to the Queen and King during the coronation concert.
Royals bow to Charles at Coronation Concert
Prince George and Princess Charlotte notably followed their father's example and did not appear to bow or curtsy to Queen Camilla. According to royal protocol, Queen Camilla is more senior than the Prince of Wales, and would usually be received with a bow.
This deliberate gesture was believed to be a response to Camilla's recent behavior. An insider revealed: "That obvious insult raised eyebrows big-time. Apparently, Kate was seething over commands Camilla made about coronation guests and decided to make her angry feelings very obvious."
A body language expert believes the Prince of Wales may have found it unnatural to perform such a gesture to his stepmother. Instead, Judi James said his gut instinct could have seen him subconsciously side with his late mum, Princess Diana.
What Kate called the Queen. While the rest of the world was required to address Queen Elizabeth as Ma'am or your majesty, those closest to her are allowed to refer to her as Mama, according to Ingrid Seward, the editor of Majesty magazine.
"The general rule of thumb to remember is that a Royal Highness does not curtsy to another Royal Highness," Myka Meier, an etiquette expert and the author of the book Modern Etiquette Made Easy, tells PEOPLE.
A friend of the Duke and Duchess of Edinburgh told the Mail on Sunday: “Sophie is relieved. She no longer has to curtsy to someone in the family who has not only left Royal duties but has spent the past three years criticising the institution that Sophie works so hard to support.”
Surprisingly, Princess Anne forms a genuine bond with Meghan Markle, defying expectations and showing a fondness for the Duchess of Sussex.
So, what's the deal? According to the royal rule book, female members of The Firm must curtsy to the most senior members of the monarchy – currently King Charles and Queen Consort Camilla – whilst their male counterparts must bow their heads.
Prince Harry joined in showing respect to the newly crowned King Charles with a bow on coronation day.
