Quiz: Who said it, Prince William or Prince Harry?

Princes William and Harry have always been close, from their early years as friends and playmates exploring their palatial surroundings to young men mourning the tragic loss of their beloved mother.

Prince Harry, 31, is a loving uncle to 33-year-old William's children, two-year-old Prince George and 11-month-old Princess Charlotte, and a close brother-in-law to the Duchess of Cambridge.
