Britain's royal family has a new addition following the birth of Princess Eugenie and Jack Brooksbank's baby boy at the Portland Hospital in London on Tuesday, Feb. 9, 2021.

Queen Elizabeth led in welcoming the family's newest member in a statement expressing her delight over the baby news. Buckingham Palace said that the Brooksbank baby, who weighed 8lbs 1oz, and his mother are "both doing well" after the delivery.

Incidentally, Portland Hospital is also where Eugenie was born 30 years ago to the Duke and Duchess of York, Prince Andrew and Sarah Ferguson.

Eugenie is Queen Elizabeth's sixth grandchild and her baby is Her Majesty's ninth great-grandchild. The baby is also now the 11th in line to the throne after his mom but he will likely not have any royal titles since his father, a commoner, has no titles as well.

The Brooksbank couple has not yet announced the name of their son but the princess has broken royal protocols by immediately sharing a photo on Instagram. Posting a black and white shot, the baby photo simply showed his tiny hands as he's held by his parents. Eugenie captioned the photo with three blue hearts.

Eugenie's uncle and aunt, Prince Charles and Camilla, also congratulated the Brooksbank family via their Clarence House Twitter account. Kate Middleton's brother, James Middleton, posted a message of congratulations in comments on Eugenie's personal Instagram as well.

According to Town & Country, Prince Harry and Meghan Markle also sent their congratulations in private to Eugenie and Jack. The Sussexes and Brooksbanks are quite close as Harry and Eugenie are each other's best friends in the royal family. Harry and Eugenie have also agreed to a living arrangement, where the Brooksbank may stay at the Sussex pair's Frogmore Cottage in Windsor as they raise their new baby.

Meanwhile, royal expert Victoria Arbiter said that withholding the baby's name is expected as Eugenie and Jack may want "a little private time" before they publicly reveal more details about their newborn. Members of the royal family also carry a great responsibility in choosing their baby's names so they have to be certain of their pick.

Royal fans think that the Brooksbank baby will be named Arthur, a very popular royal family choice. But others believe that Eugenie's baby will be named after her dad, Andrew.
