Princess Beatrice has publicly debuted her baby bump to the world at Wimbledon on day 10 of the tennis championships in London.

The royal was seen alongside her husband Edoardo Mapelli Mozzi, as they sat in the royal box at centre court for the first time out and about since their pregnancy was announced.

The couple were joined by Sophie, Countess of Wessex, as they sat to watch Ash Barty get through to her first Wimbledon final and defeat Germany’s Angelique Kerber in the women’s singles semi-final.

The 32-year-old was glowing and vibrant in a polka dot design by Self-Portrait.

Beatrice and Edo will celebrate one year of marriage on July 17.

The pair tied the knot in a private ceremony at The Royal Chapel of All Saints at Royal Lodge, Windsor.

Buckingham Palace announced their pregnancy in May, saying, “The Queen has been informed and both families are delighted with the news”.

Prince Andrew and Sarah Ferguson’s eldest daughter is due to give birth sometime between September and November, according to the Palace.

The York Bub will be the second grandchild for the Duke and Duchess of York, after Princess Eugenie and her husband Jack Brooksbank, welcomed their son, August, in February this year.

The baby will also be a younger sibling to Edo’s five-year-old son, Wolfie, from a previous relationship.
