The Queen isn't just your run-of-the-mill family matriarch.
If you happen to be one of her children or grandchildren, then you need to defer to her on some key issues, like baby names and getting married.
Back in 2011, the Queen made a declaration of consent for the now Duke and Duchess of Cambridge to marry.
They were referred to as: "Our Most Dearly Beloved Grandson Prince William Arthur Philip Louis of Wales, K.G. and Our Trusty and Well-beloved Catherine Elizabeth Middleton."
Fast-forward to 2018, and the Queen once again had to give her formal consent for Harry and Meghan to tie the knot , which she obviously did.
William and Harry had to get their grandmother's approval because of the Royal Marriages Act, which originally dictated that all royal family members needed consent from the monarch in order to marry.
But Eugenie didn't need to, and neither will Beatrice, should boyfriend Edoardo Mapelli Mozzi propose.
Whereas a few years ago they would have needed the Queen's royal seal of approval, a change to the law was made in 2013.
Now, only the first six people in line for the crown have to seek the monarch's consent, which sounds a lot simpler and more straightforward.
As it stands, this means Prince Charles (already married), Prince William (already married)Prince George (too young to marry), Princess Charlotte (too young to marry) and Prince Louis (too young to marry).
At the time of getting engaged, Prince Harry was number six as Prince Louis was not yet born. Now he's number seven and, with the birth of baby Archie, Beatrice is number nine.
It seems the further down the line you go, the more freedom you get.
