The Duke and Duchess of Cambridge left baby George with a babysitter this morning so they could shock commuters at High Street Kensington.
But it’s all for a good cause as the pair’s surprise visit was in aid of the Poppy Appeal volunteers, who are currently fundraising across the city for the good cause.
According to reports, the young Royals spent about 10 minutes chatting to all the Royal British Legion fundraisers at the station, before being mobbed by stunned underground passengers and shoppers in the area.
Everyone seemed delighted to see them, including a busking volunteer who decided to serenade the new parents by singing the classic Ben E. King hit Stand By Me.
Royal protection officers had to call for more uniformed police to man the concourse area as they couldn’t cope with the sheer volume of Londoners and tourists desperate to see the couple.
Looking smart as always, Kate looked picture perfect in her previously worn red LK Bennett coat, arranging three red Poppy Appeal flowers into a mini bouquet which she pinned on her coat.
A trendsetter as usual, the young mum might also be starting a new craze with her trio of poppies, as one volunteer admiringly said: "I must do it when I get home."
Wills looked equally smart in a navy suit, blue shirt and red and navy striped tie, although he chose to just pin one poppy to his lapel.
Everyone in the vicinity took out their camera phones to capture a photo of the Duke and Duchess of Cambridge in action.
Shocked Poppy Appeal volunteer Tim Connolly – who had a brief chat with Kate and Wills – told The Mirror: "It was a surprise. We were told we would be having VIPs here today but not who.
"It was a shock, very much so.
"William picked up the tin and saw it was full and said 'well done'."
Prince William – who left his post as an RAF search and rescue helicopter pilot in September – has always been a passionate supporter of The British Legion and the Poppy Appeal.
Kate too has been keen to support the armed forces and was very chatty and smiley during the meet and greet with the volunteers and military personnel at the tube station.
The 31-year-old spoke with Corporal Steve Johnson, an RAF recruitment officer from Newcastle, who is busking at Tube stations across London to raise funds for the appeal.
"Kate asked what kind of music I'd been playing," he said. "She asked me to play but then said don't because it's too busy.
"Kate was more interested in the music, while William was more concerned with the day itself and how the appeal was going.
"Lots of people are ecstatic to see them."
Earlier this morning the royal couple met some 2,000 uniformed personnel, veterans and their supporters, who will hit the streets of the capital ahead of Remembrance Day, to commemorate the end of the First World War in 1918.
Fundraisers will be at 80 Tube and train stations across London's transport network and at hubs including Covent Garden, where a stage has been created for military performances throughout the day.
Organisers are aiming to raise more than £1 million in a single day.
