It's no secret that Duchess Meghan and Prince Harry are among the most followed couples in the world today, so it comes as no surprise that they would go under a guise from time to time.
The royal couple are not known as simply "Harry and Meghan" to their bodyguards.
Nope, they're not even known as "Haz and Megs". "H and M" is also an absolute no-goer.
In fact, Harry and Meghan are reportedly known by a secret code name that would be tough to relate back to the couple - until you think about their royal title.
According to The Sun, the two are referred to by their royal initials: "DS" - standing for the Duke and Duchess of Sussex.

Better yet, The Sun claims their bodyguards have extended their names to be "David Stevens" and "Davina Scott" - how apt.
With a flurry of people waiting to capture their every move, it's no wonder the royal couple go by code names to their security guards.
A royal source revealed to Daily Star that it is "far too risky" to call Harry and Meghan by their actual names.
"If anyone got hold of a phone belonging to a royal aide or security team member, they won't find Harry Windsor and Meghan's names in it," they said.
They aren't the only royals to have their own code names.
Prince William and Duchess Catherine also go by the pseudonyms Danny Collins and Daphne Clark.
While it might be hard to think of William as a Danny, their initials again give it away - "DC" - standing for the Duke and Duchess of Cambridge.
The code names are certainly fun, but we'd prefer to call the royals by the names we know and love them by.
Meghan and Harry are set to arrive on Australian shores next month, where they will visit Sydney for the Invictus Games. They are also set to visit Melbourne, Fraser Island and Dubbo.
We'll be keeping an eye out for any calls from a David or Davina!
