The Duke and Duchess of Westminster are parents! Hugh and Olivia Grosvenor welcomed their first baby — a girl named Cosima Florence Grosvenor — in London on Sunday, July 27.

“The Duke and Duchess of Westminster are thrilled to announce the birth of their baby daughter,” read a statement obtained by PEOPLE. Both the Duchess and Cosima are doing well,” the statement continued. “The Duke and Duchess now look forward to spending this special time together as a family.”

The couple first announced they were expecting earlier this year. “The Duke and Duchess of Westminster are very pleased to share that the Duchess is expecting a baby in the summer,” a spokesperson for the couple said in a March 12 statement. “The couple are delighted with the news and are very much looking forward to starting a family together.”

It’s possible the Duke and Duchess could name Prince William as their child’s godfather, as the prince is a close friend of Hugh’s, who is godfather to William’s eldest son, Prince George, and is also godfather to Prince Harry’s son, Prince Archie.

William, 42, and George, 11, were recently spotted out with Hugh and Olivia for an Aston Villa soccer game on April 15, when the group watched the team’s Champions League quarterfinal against Paris Saint-Germain at Villa Park in Birmingham, England.

When Aston Villa — a favorite team of William and George — scored, Hugh and Olivia jumped up from their seats and hugged in celebration. The couple’s energetic appearance marked one of their first public outings since first announcing their pregnancy news in March.

The birth of their baby comes about a year after the pair tied the knot on June 7, 2024, in a stunning society wedding at Chester Cathedral.

Hugh is the richest person in the U.K. under 40, and he was widely considered to be one of the most eligible U.K. bachelors prior to his relationship with Olivia. He has many close ties to the British royals as a godson of the King, and his mother is godmother to Prince William.

His relationship with Prince William was on full display at his wedding, when the royal served as an usher at the event and helped guests — including Princess Eugenie — find their seats.
