It was the society wedding of the year. On June 7, billionaire Hugh Grosvenor, the 7th Duke of Westminster, wed Olivia Henson, 31, a food company account manager, at England’s historic Chester Cathedral. On hand to help his childhood friend on his big day, future king Prince William. Noticeably absent? Hugh’s other royal pal, Prince Harry.

Hugh’s family has been close to the royals for generations,” a source exclusively tells In Touch of the godfather to William’s son Prince George, 10, and Harry’s older child, Prince Archie, 5.
But with the brothers still feuding, it was clear both couldn’t attend, lest their drama distract from the pomp — especially after William, 41, was tapped to be an usher.

Although Harry and his wife, Meghan Markle, were invited, the source explains, “a delicate decision was made and the Sussexes respectfully declined.”

Harry has sacrificed more than wedding invites. Since stepping down from royal duties four years ago, the 39-year-old has suffered a string of losses. The recent blows: being cut off from his father, King Charles III, 75, and sister-in-law Kate Middleton, 42, as they each battle cancer.
