Britain's Princess Eugenie and her husband Jack Brooksbank are "very pleased" to be expecting their third child, due this summer, Buckingham Palace has said.
Britain's King Charles III is "delighted" with the news, while the couple's sons, August, five, and Ernest, two, are "very excited" to welcome a younger sister or brother to the family, the palace said.
In a photograph shared by Princess Eugenie, 36, Ernest, wearing a Chelsea football kit, and August, wearing a long-sleeved grey t-shirt, can be seen holding a picture of a baby scan.
In a statement, Buckingham Palace said: "Her Royal Highness Princess Eugenie and Mr Jack Brooksbank are very pleased to announce that they are expecting their third child together, due this summer.
"August (aged five) and Ernest (aged two) are also very excited to have another sibling join the family.
"His Majesty The King has been informed and is delighted with the news."
The baby, who will not be a HRH (His Royal Highness or Her Royal Highness), will be born 15th in line to the British throne, with their great uncle the Duke of Edinburgh, moving down to 16th place.
He or she will also be the 15th great-grandchild of the late Queen Elizabeth II, and the third to be born since her death in 2022.
The new arrival will be the fifth grandchild of Andrew Mountbatten-Windsor, following the birth of Princess Beatrice's daughter Athena Mapelli Mozzi in January last year.
Jack Brooksbank celebrated his 40th birthday on Sunday, with Princess Eugenie marking the occasion by sharing photographs on her Instagram story of her husband relaxing on a beach with the caption "happy 40th my love".
The couple married in St George's Chapel, Windsor Castle, in October 2018, and welcomed their first child, August, on 9 February 2021. His younger brother, Ernest, was born on 30 May 2023.
