Posting a series of sweet photos that captured herself with Beatrice, 36, and Beatrice’s daughter Sienna, 3, Ferguson captioned the carousel, “A very proud GiGi/Mum today.

Such an incredible blessing and an embrace to my heart. Wolfie, August, Ernie and Sienna will be over the moon to have the fifth member of the five aside!

The Duchess of York’s Instagram post also included a heartfelt passage that expanded on her elation.

“Darling Beatrice. Words can’t quite express the joy and excitement I feel as you and Edo prepare to welcome another precious addition to your beautiful family,” the passage, which was written in pink text against what appeared to be a dulled photo of Beatrice with a young Sienna, read.

“Becoming a granny again fills my heart with so much happiness and gratitude.”
