The proud mum shared two photos of the newborn sleeping in a Moses basket, with one photo showing her eldest son August gently patting baby Ernest on the head.
The caption read: “Jack and I wanted to share the news that we had our little boy, Ernest George Ronnie Brooksbank on 30th May 2023 at 8.49 weighing 7.1lbs.
“He is named after his great great great Grandfather George, his Grandpa George and my Grandpa Ronald. Augie is loving being a big brother already.”
The pair, who will celebrate their fifth wedding anniversary in October, revealed they were expecting their second child in an Instagram post back in January, sharing a photo of August kissing his mother’s growing baby bump.

Meanwhile, Eugenie’s aunt, the Princess Royal, will also become 17th in line to the throne, having been third in line at the time of her birth in 1950.
Does Princess Eugenie’s second baby have a royal title?
Eugenie and Jack’s second child do not have a royal title, as their children take their rank from their father. He is plain Master Brooksbank.
Where do Princess Eugenie and Jack Brooksbank live?
Eugenie and Jack’s main residence is Ivy Cottage at Kensington Palace in London, with Eugenie’s sister, Beatrice, living nearby at St James’s Palace.
The couple split their time between the UK and Portugal due to Jack’s work commitments. He is working with property tycoon Mike Meldman, who is managing a 300-home development at the CostaTerra Golf and Ocean Club.
It has not been disclosed how long Jack’s project will last, but Portugal certainly is the perfect place for children with so much to see and do.
