Turns out the Duchess of Cambridge has more names than we originally thought.
Ever since she married Prince William in 2011, Kate has been formally known as the Duchess of Cambridge. She is also, on occasion, referred to by her maiden name; Kate Middleton.
However, the public rarely call the royal figure by her actual name: Catherine.
In fact, Catherine only became Kate when she began studying at the University of St Andrew’s.
But just like her family and childhood friends, Prince William still calls his wife Catherine.
Prince Harry, meanwhile, has a different nickname. In The Telegraph‘s Mad World podcast, he referred to the Duchess as Cath.
Kate was asked about the name during an interview with BBC Radio 1. “Everyone calls you Kate, don’t they?” presenter Scott Mills asked the Duchess.
“I will answer to most things,” she replied.
There you have it. You can call Kate whatever you like. (But best not to try any wild names just in case.)
