The royal couple, 41, were both guests of honour at the event held at St Thomas’ Hospital in London yesterday to celebrate the 75th anniversary of the NHS.
The party was hosted by NHS Charities Together – of which William and Kate are Patrons – and television presenter Mel Giedroyc, who previously presented the Great British Bake Off.
Ahead of the event, the royal couple arrived early to help set up in the marquee outside of the Westminster hospital.
After they had laid some tablecloths, William turned to Mel and asked how she prepares her scones when having afternoon tea.

The comedian responded: ‘I go jam and then cream because I think jam is heavier and then the cream sits [better].’
Weighing in on the debate, Kate agreed and confidently said: ‘I do jam and then cream.’
Pausing for dramatic effect, Prince William stopped to look at the scone spread in front of him.
He then joked: ‘I go with whatever is closest to me!’
While Mel burst into giggles, Kate gave her husband a loving smile before also laughing at his quip.
The debate over what order to apply your cream and jam has been raging for 1,000 years in the UK – with Devonians preferring cream first while the Cornish opt for jam to begin with.
In March 2018, former royal chef Darren McGrady – who worked for the late Queen for over a decade – revealed that jam is always put on scones first at Buckingham Palace garden parties.
Elsewhere in the video, the couple were asked to help decorate some blue cupcakes.

William was decidedly more heavy-handed than his keen baker wife as he piped on a generous helping of icing.
‘Is that any good?’ he asked, as Kate burst out laughing, putting her hand over her mouth.
Alice Fevronia – who appeared on the 2019 Great British Bake Off – also joined the couple and helped to make the cake.
Kate looked suitably stylish in a £1,515 blue Alessandra Rich dress – which she has previously worn to Wimbledon – alongside a pair of drop earrings.
The party was attended by people representing the incredible achievements of the NHS over the past 75 years.
After the guests arrived in the wellbeing garden of the hospital, the royal couple emerged with a huge birthday cake to gasps of surprise.
They then sat down to chat to some of those who were invited, which included Aneira Thomas, the first baby born on the NHS, as well as medical research pioneers and those who had been on the frontline tackling Covid-19.
They also spent time with Blanche Hines, who worked as a nurse for nearly 50 years after arriving in the UK as part of the Windrush generation.

Mrs Hines inspired two more generations of her family to work for the NHS. ‘The things some of them have done is incredible,’ the Prince marvelled.
‘It’s a fantastic opportunity to be able to say thank you all the way down,’ the Princess said.
‘That’s why William and I wanted to come here and say thank you and congratulations and happy birthday.’
The Prince and Princess concluded their visit with a video message for the entire NHS, holding up signs and saying: ‘Wishing everyone a very happy 75th birthday for the NHS. Thank you so much for all you do.’
The Prince and Princess of Wales became Royal Patrons for NHS Charities Together in December 2020, at the height of the pandemic.
The charity’s 2020 Covid-19 Urgent Appeal raised over £160million. It has since distributed almost £100million to reach every NHS Trust around the UK.
Donations have funded thousands of projects including mental health support for staff and training and equipment for community first responder volunteers.
Mel Giedroyc said it was an ‘utter privilege’ to be involved, adding that people were ‘so delighted’ by the ‘quintessentially lovely, British day’.
