Prince William stuns internet with gesture after meeting deaf man: 'This warms my heart'

It's back to work for the Duke of Cambridge, who, on Monday, joined Prince Harry, Prince Charles and Queen Elizabeth at her Sandringham Estate to discuss the fallout from Harry and Meghan's royal shakeup.

On Tuesday morning, Prince William was spotted dropping off Prince George and Princess Charlotte at school in South London before making his way to Buckingham Palace to lead an investiture ceremony. Both William and Charles regularly fill in for Her Majesty at these royal occasions, which honors community leaders as Orders of the British Empire or through knighthoods.

Despite the turbulent week, a particularly heartwarming moment from the Duke of Cambridge's ceremony has gone viral.

To honor deaf television presenter Alex Duguid MBE, who has signed the show "Emmerdale and Coronation Street" for the deaf audience for decades, Prince William communicated his congratulations in British Sign Language. Duguid could be seen beaming in response to the sweet gesture, a moment that was captured by Kensington Royal on Instagram.

"Alex has been the face of popular British TV shows Emmerdale and Coronation Street for its deaf audience for decades, as a British Sign Language (BSL) interpreter," the photo's caption reads. "He is an example of how profoundly deaf people can have an impact on their community, their peers and their country. He is passionate about BSL and the need to promote and protect it."

The special moment has been applauded by royal fans for the heartwarming and meaningful gesture.
