The pair watched the start of the Ladies’ Singles Semi-Final matches on centre court today.
This marks Beatrice’s first public outing while pregnant.
She and her husband Edoardo married last year, during lockdown.
While this will be her first baby, her husband has a son, Wolfie, from a previous relationship.
Fans praised the royal’s look on Twitter. One wrote: “Loved the chill/cool vibes The Countess of Wessex exudes. And Princess Beatrice is glowing. Her and Edo are indeed a lovely pair.”
