Princess Beatrice steps in for pregnant Princess Eugenie as royal's due date approaches

Beatrice appeared at a show garden by Horatio's Garden, which has been designed for people with spinal injuries.

Princess Eugenie is a patron of the charity and shared a touching tribute on Instagram.

The social media post included photos of Beatrice and Edo at the event.

Eugenie wrote: "I'm such a proud patron of this charity and my sister loved visiting yesterday."

Earlier this month, Sarah Ferguson gave a big indication of when her daughter's due date is.

The Duchess of York told Hello!: "We don't know what it is yet. But the baby is due by the end of May, I think. So it's any minute now."

While Princess Eugenie did not attend the Chelsea Flower Show, several other members of the Royal Family did.

King Charles, Camilla and the Princess of Wales all visited the event on Monday.

This week, a royal insider shared his disappointment at the lack of reporting on the King's engagement.

An insider told the Daily Mail: "With his love of horticulture, His Majesty's appearance at Chelsea was an important engagement.

"It's a shame that his visit with Her Majesty the Queen received less coverage than might have been expected.

"I hope they are not too disappointed."

Royal sources have expressed concern that the King and Queen's visit was overshadowed by a surprise appearance from the Princess of Wales.
