William and Kate sign Prince George's birth register

Mother's occupation: Princess of the United Kingdom

What does Kate, duchess of Cambridge, write under the category of “occupation” on her baby’s birth registration?

She does wear a lot of hats: fundraiser, diplomat, socialite. And she did have a career with her family party planning company before she married Prince William.

It appears her official occupation, as written on the birth registration for Prince George, is Princess of the United Kingdom.

Likewise, Prince William is a search and rescue pilot with the Royal Air Force, but he lists his higher calling under the occupation category: Prince of the United Kingdom.

Here’s the full birth certificate, in a picture tweeted by Clarence House, the official Twitter account for the duke and duchess of Cambridge.
