The announcement came less than a year after Hugh and Olivia tied the knot in what was described as the society wedding of the year. The Duke and Duchess got married in June of 2024 at Chester Cathedral. The bride looked elegant for her big day wearing a dress by Emma Victoria Payne. The Prince of Wales reportedly served as an usher at the couple's wedding.

Hugh is one of Prince George's godparents. When it came to picking godparents for their firstborn, a source told PEOPLE (via E! News) in 2013 that the Prince and Princess of Wales "wanted to include family and friends and reflect their life on both sides." In addition to being George's godparent, the Duke is reportedly a godfather to Meghan Markle and Prince Harry's son, Prince Archie. Hugh is also one of King Charles' godchildren.
