And on the big day, doting father Mike shared an insight into the celebrations as they stood in a wide-open area surrounded by dozens of colourful balloons. While Mike proudly stood holding his lot aloft, Zara playfully hid under hers, and even got them styled to look they would work as a hat for the Ascot celebrations.

On the day, Zara wore a precious Greek tiara that belongs to her mother, Princess Anne. The 'something borrowed' piece consists of a brilliant-cut diamond surrounded by a glittering wreath.
