He's not a prince! Three interesting facts about Princess Eugenie's baby

Britain's newest royal baby has made his debut.

Buckingham Palace announced on Tuesday that Princess Eugenie had given birth to a son with husband Jack Brooksbank. The new mom was quick to share a sweet photo on her Instagram account showing her and her hubby holding their little one's hand.

Princess Eugenie is the daughter of Queen Elizabeth's scandal-ridden son, Prince Andrew, and his ex-wife Sarah Ferguson AKA Fergie. The baby is the pair's first grandchild, and the queen's ninth great-grandchild.

Here are some other facts about the latest addition to the Windsor family:

1. HE'S NOT A PRINCE

Princess Eugenie may have a royal title, but that doesn't mean her new baby will have one too.

Why not? It's rather complicated and all comes down to a decree issued by one of the princess's ancestors, King George V, in 1917.

According to Time magazine, this decree states that the British sovereign's children and their grandchildren (in the male line) are automatically granted the title of prince or princess. That's why as the daughter of Queen Elizabeth's second son, Prince Andrew, Eugenie is a princess.

When it comes to the sovereign's great-grandchildren, however, King George V declared that only the oldest son of the Prince of Wales’ eldest son would be given a grand royal title.  

So, in terms of this rule, the only one of Queen Elizabeth's great-grandchildren who qualifies is Prince George, Prince William's firstborn son and Prince Charles' oldest grandson.

However, in 2012 Queen Elizabeth issued a decree granting the title of prince or princess to all of Prince William's children. That's why his other children, Princess Charlotte and Prince Louis, have royal titles.

Told you it was complicated!

He may, however, still be given a title should the Queen decide to issue one to his father or issue a Letters Patent amending the rules, reports Hello! magazine.

2. HE'LL BE 11TH IN LINE TO INHERIT THE THRONE

The baby might not automatically qualify for a royal title, but he does qualify for a spot in the succession. He'll be 11th in line to inherit the crown from Queen Elizabeth.

Here's the pecking order:

1. Prince Charles (Queen Elizabeth's eldest son)
2. Prince William (Prince Charles' eldest son)
3. Prince George (Prince William's eldest son)
4. Princess Charlotte (Prince William's daughter)
5. Prince Louis (Prince William's youngest son)
6. Prince Harry (Prince Charles' youngest son)
7. Archie Mountbatten-Windsor (Prince Harry's son)
8. Prince Andrew (Queen Elizabeth's second son)
9. Princess Beatrice (Prince Andrew's eldest child)
10. Princess Eugenie (Prince Andrew's youngest child)
11. Princess Eugenie's son

3. HE'S NOT THE ONLY BRITISH ROYAL BABY WHO'LL BE BORN IN 2021

Princess Eugenie's first cousin, Zara Tindall, is also expecting. The baby will be Tindall's third child with former English rugby player Mike Tindall.
