Eugenie is the younger daughter of Prince Andrew and Sarah Ferguson, the Duke and Duchess of York, who will be first-time grandparents.

Sarah Ferguson took to Twitter to celebrate the news, writing, in part, \"Welcoming a new baby into the York family is going to be a moment of profound joy.\"

I am so excited by the news that Eugenie and Jack are expecting their first child. Thrilled for them both and in my 60th year cannot wait to be a grandmother. Welcoming a new baby into the York family is going to be a moment of profound joy pic.twitter.com/nGtMkqNTKJ

The new baby will be the ninth great-grandchild for Eugenie's grandparents, Queen Elizabeth and Prince Philip.

Eugenie, also a cousin of Prince Harry and Prince William, married Jack Brooksbank in St. George’s Chapel, Windsor, in October 2018.

Prince William's two oldest children -- Prince George, 7, and Princess Charlotte, 5 -- served as page boy and bridesmaid, respectively.

Her exchanging of vows took place less than six months after Prince Harry and Duchess Meghan's high-profile wedding in the same chapel.
