Kate Middleton is one of the most well-known women in the world, so it’s logical that she’d like some solitude from time to time.

The Duke and Duchess of Cambridge are rumored to have secret code names that they use on excursions and in their spare time.

When Kate goes abroad, she goes by the nickname Daphne Clark, and William goes by the alias Danny Collins, according to the Express.

Both have the initials DC, which are the same as their titles of Duke and Duchess of Cambridge.

Kate isn’t the only one who goes by this moniker when she wants to keep things low-key.

The royal mother-of-three allegedly let one of her monikers escape on a shopping trip in London, according to The Mirror.
