When we think of royal rule breakers, a few key people come to mind.

Of course, Diana Spencer tops the list.

Doesn’t all of that sound a little familiar?

So where does that leave the rest of the royals?

Are they all royal rule followers who stick to the protocol to a tee?

Or do they break some barriers down (of course, in less cataclysmic ways)?

As it turns out, King Charles III has broken royal rules himself on more than one occasion.

Additionally tied to Charles in an equally profound way is his brutal separation and divorce from Diana Spencer.

This unspoken rule exists for several reasons.

Alas, Charles threw the rule book out the window and took a selfie with a fan anyway.

When he grasped what was going on, Charles smiled for the snap.

Charles was attending Gordonstoun School when he ordered a cherry brandy while hanging out with some classmates.

It was not only his first drink ever, but he paid for it despite his royal status!

It will be a very special day for us and our families," Charles announced (viaPeople).

I’m just coming down to Earth."

When Charles became king, Camilla adopted the title of queen consort.

He proceeded to write “Charles 2010” and even said sorry for his “shaky writing.”

“When I first spoke publicly about the environment, many wondered if my sense of urgency was misplaced.

We know what we need to do.

King Charles III, however, has opted to break this unwritten rule on more than one occasion.

The first time was when he married Queen Camilla in 2005.

It was a private ceremony, so it was probably easier to bend the rules a little.

Charles found himself defying tradition once again when Prince Harry got married.

Instead, Charles did the honors.

Charles happily obliged, royal protocol be damned.

This included forgoing the traditional breeches and silk stockings his predecessors wore at their coronation ceremonies.

Instead, Charles went for a more modern approach by wearing his military uniform.

We couldn’t agree more.

William, Prince of Wales, however, still honored the custom.

Passed down in families, these cloaks have been donned at coronation ceremonies since the 17th century.

“Different types of occasions call for different types of behavior,” royal author Judy Wade added.

According to the outlet, this was the couple’s third official public kiss.

“I need to be seen to be believed,” the queen reportedly said (viaHR Morning).
