But it wouldn't automatically become a Prince or Princess, because titles within the royal family were limited by the Queen's dad, King George V, in a right in 1917.
Britain's Princess Eugenie and her husband Jack Brooksbank have released four official wedding pictures following their marriage at St George's Chapel, Windsor Castle on Friday.
Ellie was joined by her fiancé Caspar Jopling at the bash laid on by Prince Andrew and Fergie. Once she reached the altar and stood by his side, he removed them and handed them to best man, brother Thomas.
Two page boys and six young bridesmaids appear in both portraits.
The first showed the couple sharing a kiss in the Scottish State Coach, upon its return to Windsor Castle following the Carriage Procession.
Princess Eugenie Shows Off Her Back Scars in Royal Wedding Gown
The dress features a neckline that folds around the shoulders to a low back that drapes into a flowing full length train. Eugenie sparkled as she donned an emerald tiara loaned to her by the Queen - and previously owned by the Queen Mother.
In the fourth photograph, the newlyweds are pictured at the York family home, Royal Lodge in Windsor Great Park, ahead of the private evening dinner.
The Duke and Duchess of Cambridge were seated next to the Duke and Duchess of Sussex, who had to skip Eugenie and Jack's second wedding day due to their royal tour of Australia.
Her dress, with a flowing skirt and angular neckline, was designed by Zac Posen.
Also, she isn't a "working royal" meaning she doesn't work for the Queen completing royal duties. It was originally a brooch commissioned in 1830 and passed down to Queen Victoria in 1837, and then to Queen Elizabeth in 1952.
So with the couple being tipped to welcome a new addition to the Royal Family over the coming years, Daily Star Online has revealed photos of what the tot would look like.
Eugenie is a director at London's Hauser & Wirth art gallery, and Brooksbank owns a wine wholesale business and is European brand manager for Casamigos Tequila, which was co-founded by USA actor George Clooney.
