A photo of Prince George's birth registry was recently released, with Prince William listing wife Kate Middleton as "Princess of the United Kingdom" as her occupation, US Weekly reports. What's going on here?

Prince William listed himself as "Prince of the United Kingdom" in the register he signed this morning, brought specially to him at Kesington Palace by the Westminster City Council Registrar. Most people have to travel themselves to register their new baby, but being a royal comes with its perks!

Though the term "princess" isn't technically accurate, as Middleton won't become one until Prince Charles becomes king, Prince William did specify on the form that his wife is the Duchess of Cambridge. The prince seemed to take pleasure in pointing out that her job is to be the U.K. (and the world's) "princess", as Middleton is adored and revered by fans across the globe for her sophisticated style, elegance and down-to-earth take on royal. life.

The differences between princesses and duchesses can be confusing to understand, as the two titles often intersect. According to the Guardian, the Queen could have made an exception and referred to Middleton as "Princess Catherine," but decided to stick to tradition.

Just as her late mother-in-law Princess Diana did, the Duchess gave birth to baby Prince George naturally at the luxurious Lindo Wing in London, the entrance of which she first introduced the new heir to the throne to the world. And even though the Duchess may not officially be a princess yet, as Princess Diana once said, "being a princess isn't all it's cracked up to be."

One thing, however, is for certain: Prince George is an official heir to the throne, currently third in line behind Prince Charles and his father Prince William. If Kate Middleton had a girl instead, the child would have been the first female heir in British Royal history to have the chance to become Queen before her younger siblings, according to Celebrity Net Worth.

Despite the "missed" opportunity for such an historic event, we are delighted that Prince George has arrived safely to the world and is doing well, a happy and healthy boy with a "big appetite," according to royal sources, as the Duchess has gotten the knack of breastfeeding her son and has subsequently become another source of inspiration for women who choose to breastfeed their own children.
