The Princess of Wales appeared to take the lead as she and Queen Consort Camilla watched the annual Remembrance Sunday service today, according to a lip reader.
The two royal women stood on the balcony of the Foreign Office, overlooking the Cenotaph, where wreaths were laid by King Charles and other royals to honour the nation's war dead for the first time since the death of the Queen.
They both wore elegant black coats and hats and each had three poppies pinned to them as well as diamond brooches.
There was also a poignant empty space on the balcony, where the late Queen had stood to watch the emotional service in previous years when Charles, then Prince of Wales, would lay a wreath on her behalf.
As the service, which included a poignant two-minute silence, came to a close, Kate and Camilla could be seen exchanging a few words before exiting the balcony.
And lip reader Jeremy Freeman told the Mirror what he believes was said - and it appears it shows that a confident Kate was happy to lead the two women.
He believes that Kate said to Camilla: "Shall we go in now?" before the Queen Consort nodded and they left the balcony.
It comes as today's moving Remembrance Day service saw the royals out in force.
The King lay a new poppy wreath incorporating a ribbon of his racing colours, with the design a tribute to the ones used by both his late mother and his grandfather George VI.
He wore the great coat of a No.1 Field Marshal, laid his wreath and took a few steps back before saluting and returning to his place. A wreath was also laid on the Queen Consort's behalf for the first time.
Dressed in his RAF uniform, Prince William lay the same wreath previously placed by his father, who held the title Prince of Wales for more than 64 years before his accession to the throne. It features the white Prince of Wales feathers and bears a new ribbon in “Welsh red”.
Also present were the Earl and Countess of Wessex, Princess Anne and Vice Admiral Sir Tim Laurence, the Duke and Duchess of Gloucester and the Duke of Kent.
The Queen, who died just nine weeks ago at the age of 96, considered Remembrance Sunday, which commemorates the war dead, one of the most significant and important engagements in the royal calendar.
The nation’s longest reigning monarch, who lived through the Second World War as a teenager and was head of the armed forces, only missed seven Cenotaph services during her reign, including last year due to a back sprain.
