James Middleton and Alizee Thevenet have Cassian Grantsome royally good news to share.

Kate Middleton's younger brother announced he and his wife are expecting their first baby. In a series of snaps shared to Instagram July 5, Alizee, 32, is seen cradling her baby bump as she stood beside their dog Mabel.

"We couldn't be more excited … well Mabel might be," James, 36, wrote while paying tribute to their late dog Ella. "It was a very difficult start to the year after losing my beloved Ella, however, we will end the year with the most precious little addition to our growing family."

In fact, it was his beloved Ella who was the one responsible for James' meet-cute with the financial analyst.

"The two of us were at the South Kensington Club in Chelsea," he told The Telegraph in 2021. "Ella was lying at my feet under the table; realizing she might want some water, I trusted her to take herself to the water bowl across the terrace. However, she made a beeline for Alizee. Rather embarrassed, I went over to apologize and bring Ella back."

And the rest is history.

"Little did I know, I had just met my future wife, all thanks to Ella," he shared. "If I hadn't trusted Ella, I wouldn't have brought her to the South Kensington Club, and she wouldn't have been able to say hi to the woman who became my fiancée."

When their baby arrives, the newborn will join cousins Prince George, 9, Princess Charlotte, 8, and Prince Louis, 5 (who Kate shares with husband Prince William) and Pippa Middleton's kids Arthur, 4, Grace, 2, and 11-month-old Rose (whose dad is James Matthews).

Alizee's pregnancy comes nearly two years after the couple tied the knot in France. After their ceremony, James shared a sweet glimpse into their new life together.

"I married the love of my life surrounded by family, friends and of course a few dogs in the beautiful village or Bormes-les-Mimosas," he wrote alongside a September 2021 Instagram selfie of the pair. "Words cannot describe how happy I am."
