What did Camilla call Prince Charles?

the duchess of Cornwall called the prince of Wales a number of things I'm sure, but one known fact is that she sometimes called him "Fred" and he called her "gladys" as their pet names for each other, but also as a cover for when they had a tryst. she is also supposed to have referred to herself in a letter to Charles as "your devoted old bag" which clearly shows her very British, self-deprecating sense of humour.
