On Saturday the Prince of Wales shared the first insight into his latest project - Prince William: We Can End Homelessness, a documentary with ITV.
Prince William, 42, shared a clip of the documentary on his official Instagram account where he is asked about his motivation to make the film - and viewers are saying the same thing.
"I think it’s really important that we can try and change, and tackle, the narrative around homelessness," King Charles' son explained.
"People live with it, we see it every day in our lives, that’s something I want to challenge."
Royal followers flocked to the comments section to remark upon the Prince's likeness in the video to his late mother Princess Diana.
"He looks like his mother. Same way to talk. She would be so proud," wrote one royal follower, while another added: "Would be making his mother so proud, HRH Prince William honours her well."
A third wrote: "I’m so excited for this documentary. I have no doubts your beloved mother, who took you to homeless shelters many times, is so proud of you."
The late Princess of Wales took her young sons William and Harry to homeless shelters during their childhood, encouraging them to have an understanding of life outside the palace.
The upcoming documentary follows the royal during the first year of his Homewards initiative, which aims to tackle all forms of homelessness.
Honouring Princess Diana
The ITV documentary isn't the only way the Prince of Wales continues to honour his mother's legacy through his charity work.
He remains the patron of Centrepoint - a role he took over from his late mother in 2005 and his first patronage. The charity provides accommodation and support to homeless people aged 16 to 25.
