Here comes the mother of the bride!
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, 58, wore a green dress with a matching hat while Beatrice, 30, stunned in blue.
The two stopped and waved to the crowd as they entered the chapel.

After the wedding ceremony, the newlyweds will also be feted by a lunch hosted by Queen Elizabeth at Windsor Castle and then a black tie evening reception at Royal Lodge.
Eugenie and Jack are also extending the party for another full day with a festival-style event complete with a fairground and food stalls on Saturday.

Ahead of the big day, Fergie helped her daughter plan the wedding.
