On the 29th April 2011, over a million people lined the streets of London as the royal wedding took place. Kate looked stunning in an Alexander McQueen custom-made dress as she arrived at Westminster Abbey. Prince William told Kate she looked beautiful before joking: "We're supposed to have just a small family affair".
Once the wedding procession had returned to Buckingham Palace Kate exclaimed: "Oh wow" as she stepped out onto the Palace's Balcony for the all-important kiss.
It was announced on the morning of the wedding that Kate would become the Duchess of Cambridge.
