This Trivia Tuesday is fit for a queen! This is the ultimate quiz for copy-Kates everywhere.
Find out how much you really know about Kate, William, Pippa, and Harry.
We dug deep into their pasts, public records, and even private voicemails that have been leaked through the years to make sure that we stump you. If you manage to get all of these questions right, we want to hear from you! Tweet at us at @CRI_Hollywood.
