Princess Eugenie, a granddaughter of the late Queen Elizabeth II and niece of King Charles, has announced the birth of her third child with her husband, Jack Brooksbank.
The couple said they were "beyond in love" with their baby girl in a post on Instagram.
Eugenie and Brooksbank already have two sons: August, born in February 2021, and Ernest, who was born in June 2023.
The Royal Family's official account on X said the King and Queen, along with other members of the family, were "delighted" to hear the news.
Eugenie, 36, married Brooksbank, a marketing executive, at St George's Chapel at Windsor Castle in 2018.
She is currently 12th in line to the throne.
The princess is the younger daughter of Andrew Mountbatten-Windsor, formerly the Duke of York, and Sarah Ferguson.
Her father's relationship with convicted sex offender Jeffrey Epstein has cast a shadow over the wider royal family in recent years. Andrew was stripped of his royal titles and public roles after the scandal and has denied wrongdoing.
Eugenie and her sister, Princess Beatrice, have maintained a relatively low public profile but continue to attend selected royal and family events.
