There is another British royal baby on the way.
Princess Beatrice, 32, and her property developer husband Edoardo Mapelli Mozzi, 37, have announced they are expecting a baby in the autumn.
A Buckingham Palace statement reads: "The Queen has been informed and both families are delighted with the news."
The baby will be the Queen's 12th great-grandchild, as Prince Harry and Meghan, Duchess of Sussex are expecting a baby girl this summer.
Prince Beatrice and Mapelli Mozzi married in July 2020, in a small private ceremony at Royal Chapel of All Saints in Royal Lodge, Windsor. The wedding was not publicly announced in advance.
The couple confirmed their engagement in September 2019 and were due to marry on May 29, 2020 at the Chapel Royal at St James's Palace, followed by a private reception in the gardens of Buckingham Palace. However, because of Covid-19 measures, they were forced to change their plans.
Their wedding was attended by Queen Elizabeth II and Prince Philip, Princess Beatrice's grandparents.
The princess wore a remodelled Norman Hartnell dress, which was previously worn by the queen, and the Queen Mary Fringe Tiara, which the queen wore at her own wedding.
The baby will be Princess Beatrice's first child, but the second baby for her husband; Mozzi is father to Christopher Woolf, 5.
News of Princess Beatrice's pregnancy comes three months after her younger sister, Princess Eugenie, 31, welcomed baby August Philip Hawke Brooksbank, on February 9, with husband Jack Brooksbank.
