The latest epic surprise to come out of the Queen's celebrations came from Kate Middleton and Prince William, who gave Notting Hill residents the surprise of a lifetime when they unexpectedly arrived at a neighborhood street party.

The Duke and Duchess took a moment to stop by a Big Jubilee Lunch on Ladbroke Grove, chatting with residents, sitting down for coffee, and taking pictures with plenty of adorable kids.

For the impromptu addition to their programme ahead of the Pageant on Sunday, Kate dazzled in yet another impossibly chic dress.

She looked fabulous as she donned the bright blue number by Alessandra Rich which featured pleats going down its front, quarter length sleeves, padded shoulders, a waist-accentuating belt, and scattered white polka-dots to top it all off. She paired the look perfectly with coordinating pointy-toed white pumps and her signature wavy long hair.

A resident who was witness to the last minute appearance shared images where both Kate and Will are seen attentively chatting with other residents, and the Duchess is even seen crouching down to listen to a little girl excitedly explain something to her, as well as sitting down in between residents to have some coffee, as her husband appeared smiling and laughing behind her.
