Yes, you're right.

Both these developments have already taken place.

However, Kensington Palace released the newborn's birth certificate on Tuesday, making this child's birth truly, completely, legally official and exciting.

The document (below) is chock full of basic nuggets regarding little Louis, such as where he was born; he gender; and the names of his parents.

One thing that jumps out to us, however, is the listed occupation of those parents.

As you can see here, William is dubbed “Prince of the United Kingdom," while Middleton is referred to as “Princess of the United Kingdom.”

These aren't titles with which we weren't already familiar of course -- it's just funny to see someone's job listed as "Prince" or "Princess."

Unlike his siblings - Prince George, 4, and Princess Charlotte, 2 - Louis’ birth certificate is typed and not handwritten.

We don't know why this is or if it means anything, but we figured we'd point it out.

We can confirm, however, that Prince William signed the document above at his Kensington Palace residence on Tuesday, May 1.

It was witnessed by Westminster City Council registrar Patricia Gordon. 

“It has been a great honor to register and formally welcome the latest addition to the royal family, Prince Louis Arthur Charles,” Gordon said in a statement, adding:

“This follows a long history of Westminster City Council registering royal bites including Prince Louis’ siblings Prince George and Princess Charlotte.”
