Britain's Princess Beatrice is expecting her first baby with her husband Edoardo Mapelli Mozzi.

The news that the couple will welcome their first baby in the autumn was announced on the official Buckingham Palace Twitter page on Wednesday.

Along with a photo of the couple on their wedding day, the palace said: "Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are very pleased to announce that they are expecting a baby in autumn of this year.

"The Queen has been informed and both families are delighted with the news."

The couple wed in Windsor in a private ceremony away from camera lenses in July last year. The Queen, Prince Philip, Sarah Ferguson, Prince Andrew and Princess Eugenie were among the small group of guests.

The 32-year-old bride borrowed the tiara that the Queen wore on her wedding day; the Queen Mary diamond fringe tiara.

The couple were originally meant to wed on May 29, but the ceremony was postponed due to Covid-19 restrictions.

Princess Beatrice's parents, the Duke and Duchess of York, were not in the photos, but the palace confirmed her father walked her down the aisle.

The baby will be the Queen's 12th great-grandchild following the arrival of the Prince Harry and Meghan Markle's second child in the summer.
