"Catherine appeared to whisper to William and laugh as he adjusted his hat."
On 15 June, Prince William and Catherine, Princess of Wales, participated in the Order of the Garter procession at Windsor Castle.
Kensington Palace released a video showing the couple sharing a private moment outside St George's Chapel while waiting for their carriage.
Catherine appeared to whisper to William and laugh as he adjusted his hat. The couple then boarded their carriage with other senior royals.
The Order of the Garter, founded by King Edward III nearly 700 years ago, is Britain's oldest and most prestigious order of chivalry.
