Here comes the mother of the bride!
Sarah Ferguson, the Duchess of York, arrived at the Saint George’s Chapel at Windsor Castle on Friday for her daughter Princess Eugenie‘s wedding to Jack Brooksbank.
Ferguson, also referred to by the nickname “Fergie,” arrived to the royal wedding alongside her oldest daughter, Princess Beatrice, who is serving as maid of honor. They both walked into the chapel ahead of the arrival of Eugenie and Fergie’s ex-husband, Prince Andrew.
Fergie wore a green dress with a matching hat while Beatrice stunned in blue.
The two stopped and waved to the crowd as they entered the chapel.
Along with Fergie, Eugenie’s royal cousins, Prince William, Kate Middleton, Prince Harry and Meghan Markle, are also in attendance.
