William’s presence at the Grosvenor wedding, along with his ongoing public appearances with the couple, including attending a Champions League match together earlier this year, has fueled speculation that he could be named baby Cosima’s godfather.
Prince Harry, who maintains a more private life in California, was invited to the wedding but agreed with Grosvenor not to attend, reportedly to avoid media tension amid his strained relationship with his brother. While Harry remains close to the Duke on a personal level—Grosvenor is said to be godfather to Harry’s son, Prince Archie—his absence from recent events may influence the final decision.
The decision remains private

At this point, no official announcement has been made. It is entirely possible that neither of the brothers will take on the godparent role, leaving the decision solely in the hands of the Duke and Duchess of Westminster.
Hugh Grosvenor, one of the wealthiest men in the UK under 40, continues to play a significant role in both business and philanthropy. Beyond his personal life, he oversees the vast Grosvenor Estate, with holdings in London’s Mayfair and Belgravia, as well as international investments. Known for his generosity, he notably donated £12.5 million to the UK’s Covid-19 relief efforts in 2020.
For now, royal watchers can only wait to see who will be chosen for this special role in baby Cosima’s life.
