In one video from the walkabout, the Duchess of Cornwall and Cambridge can be seen chatting to a woman in the crowd, receiving a warm welcome.
It's not clear in the audio what exactly the woman said to Kate, but it clearly had a big impact on the royal as she could be seen patting her hands to her cheeks several times in an amusing gesture.
She then smiled and made a cute comment, telling the other woman: "I'm going to blush!"
Meghan Markle also had a lovely moment with a member of the public during the 40-minute walkabout at Windsor.
The Duchess of Sussex went viral when she shared a hug with 14-year-old Amelka Zak, after telling her that her name was "beautiful" and thanking her for waiting.
The teenager has since spoken out about the "amazing" moment, claiming in a chat with CNN that she wanted to make sure Meghan knew she was "still welcome" in the UK after "everything that's happened".
She added: "Everyone was kind of cheering me on and I guess I felt I needed to in a way because I look up to her and it felt like the right thing to do."
