Teddy is the eldest of the ‘X Factor’ couple’s three children. They also have a three-year-old son Charlton Valentine and another daughter Colette Josephine, who they welcomed via surrogate in September.
Robbie and Ayda are notoriously protective of their children and have, up until now, kept them out of the public eye.
Mia Tindall, the four-year-old daughter of Zara and Mike Tindall will also be a bridesmaid alongside Princess Charlotte, 3, Savannah Philips, 6, Isla Philips,6, and Maud Windsor, 5.
Prince George will act as one of the two page boys, while Eugenie’s sister, Princess Beatrice, will be her Maid of Honour.
More than 800 guests, 200 more than at Harry and Meghan’s nuptials, will gather in the gothic chapel for the royal celebration.
The Queen and the royals, including the Duke and Duchess of Cambridge and the Sussexes, are expected to be out in force, alongside Eugenie’s proud parents, Prince Andrew, Duke Of York and Sarah Ferguson.
Celebrity guests are yet to be confirmed but it’s safe to say that Robbie and Ayda have already received their invite.
