While the world might call the Duchess of Cambridge by the diminutive "Kate," her birth name is, as we all know, Catherine.
However, during a trip to her old school St Andrews, in Pangbourne, Berkshire, in 2012, the 35-year-old admitted that she used to be known by the name "Squeak" among her classmates.
According to, the Duchess told pupils that Squeak was also the name of one of the school's guinea pigs.
"There was one called Pip and one called Squeak, so my sister was called Pip and I was Squeak," she revealed.
Now, with current titles including Her Royal Highness The Duchess of Cambridge, Her Royal Highness The Countess of Strathearn, Countess of Strathearn and Lady Carrickfergus, and even Princess William of Wales, we wouldn't blame her for wanting to simply be called Squeak once in a while.
