Like any other family, the members of the royal family use nicknames for each other. Nicknames can be used to protect privacy, express intimacy and affection, lighten the mood, or be simply easier to say than real names.
The Queen has been known by nicknames including Gary, Cabbage, Gan-Gan and Lilibet. The late Duke of Edinburgh, Prince Philip, was frequently called Phil the Greek, Zorba and Stavros, due to his Greek heritage.
The Duke and Duchess of Cambridge have had a series of nicknames for each other over the years. They certainly couldn't get away with using some of these today, reports The Mirror.
