The children of the Duke and Duchess of Cambridge took part in the nationwide round of applause to thank the NHS for their work treating coronavirus patients.
Prince George, Princess Charlotte and Prince Louis were on Thursday all seen clapping in a video released by Kensington Palace, where they live.
They joined people around the UK in paying tribute to the NHS staff working hard to treat coronavirus patients.
Grateful members of the public stood at their windows at 8pm to applaud the work of the healthcare workers risking their own health in the fight against the virus.
Some went into the streets, and motorists joined in by tooting their horns.
Prime Minister Boris Johnson and Chancellor Rishi Sunak also took part in the initiative, which was called Clap for Carers.
London Mayor Sadiq Khan also saluted the initiative.
Notable buildings across the UK lit up in blue to mark the nation applauding the health service.
Blackpool Tower, Newcastle's Tyne Bridge and Tower Bridge were among the landmarks to salute the NHS as part of the #lightitblue campaign.
It comes as the latest figures show 578 Covid-19 patients have so far died in the country, while the number of confirmed cases has hit 11,658.
