All aboard! The Duke and Duchess of Cambridge rode a classic 1960s Routemaster bus to surprise military personnel and volunteers who were supporting the Royal British Legion for Poppy Day. The couple took a five minute bus ride from Kensington Palace to High Street Kensington station, where thousands of RBL supporters congregated, and were joined by famous British "Carry On" actress Barbara Windsor, who is the Poppy Day Ambassador.

Poppy Day (or more formally know as Remembrance Day) has been a a memorial day since World War I to remember the members of British Commonwealth's armed forces who have died in the line of duty.

While on the short ride, the Barbara Windsor asked about the Prince George, to which Kate replied, "He's half asleep," and William added, "He's behaving himself this morning."

After disembarking the bus, William and Kate were met by the excited Poppy Day crowds. The duo greeted and spoke with volunteers, Poppy Girls, military personal and other supporters.

For the public event, Kate wore a coat by LK Bennett and William, who recently left his position as a search and rescue pilot, opted for a classic navy suit. Both Royals wore the iconic red Poppy Day pins to show their support for the fallen troops.
