Prince Harry attended the wedding of cousin Alexander Fellowes to Alexandra Finley on Friday.
The new uncle joined guests at the chapel of St Mary Undercroft at the Palace of Westminster to watch Alexander, whose aunt was Diana, Princess of Wales, marry shoemaker Alexandra.
Alexander is the son of Lord Robert Fellowes, who is married to the late Princess’ middle sister, Jane. Harry was joined by cousin Celia McCorquodale, 22, as Prince William and Duchess of Cambridge stayed home.
The groom’s father Lord Fellowes is also related to Sarah, Duchess of York and the creator of Downton Abbey, Julian Fellowes.
Wedding guests were treated to a Routemaster bus that took them to the chapel and then on to the wedding breakfast at Claridges Hotel.
The Prince, who recently became an uncle to Prince George, looked dapper in a navy blue suit with a red tie as he arrived for the wedding.
The society wedding comes just days after the Prince attended the wedding of Lady Laura Marsham and James Meade with brother Prince William and Kate’s sister Pippa Middleton.
