Princess Beatrice and her husband Edoardo Mapelli Mozzi are expecting their first child this autumn.
The two married July last year at a secret ceremony, which was held at All Saints Chapel and attended by the Queen.
This was not public due to the ongoing coronavirus pandemic.
A statement by Buckingham Palace on Twitter said: “Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are very pleased to announce that they are expecting a baby in autumn this year.”
“The Queen has been informed and both families are delighted with the news.”
The announcement is on the third anniversary of the Duke and Duchess of Sussex’s wedding, which was in Windsor on the 19th of May 2018.
Princess Beatrice and Edoardo started their relationship in October 2018 after Princess Eugenie’s nuptials. The couple’s families had been friends for a number of years.
The newest Royal Baby will be the Queens 12th great-grandchild, following the Duke and Duchess of Sussex’s second child that is due in the summer. The princess will move from 9th to 10th in line to the throne after the birth of the Duke and Duchess’s second child.
Their child will also be 11th in line to the throne.
Princess Beatrice also became an aunt in February. Her sister, Princess Eugenie gave birth to a baby boy named August.
