Prince William and Kate Middleton gave royal fans at one street party a surprise of a lifetime when they "dropped in" unannounced before taking selfies with guests.
The Duke and Duchess of Cambridge made a "last minute change" to their plans and decided to surprise revellers at the Ladbroke Grove street party in London before heading to the Platinum pageant today (Sunday, June 5).
Today marked the fourth and final day of celebrations for the record-reigning monarch who has sat on the throne for an incredible 70 years.
