In public the Royal Family are perfectly poised, but moments when we see them let their guard down really paint a picture of the people behind the titles. Nicknames are another way they show their personalities and there have been some memorable ones - Prince Philip calling Queen Elizabeth "cabbage" springs to mind.
Low-key royal couple Zara and Mike Tindall also have pet names and I was surprised when the retired rugby star revealed what his wife calls him. In woman&home's July issue, on sale now, he explains to the magazine's Royal Editor Emily Andrews that "if it's nicknames, it's Z and Mikey-T".
