On Thursday (6 October), Middleton and her husband, Prince William, were on a day-long trip to north Belfast and greeted people in the crowd.
Video footage was shared on Twitter, showing the woman confronting the royal about her visit to the country.
“Nice to meet you, but it would be better if it was when you were in your own country,” the woman, who seemed to be filming the moment on her phone, can be heard telling Middleton as she shook her hand.
The royal appeared to chuckle in shock from the sentiment but kept her composure and let the woman’s hand go.
And as she turned to say hello to others in the crowd, the woman who still had her phone out to film added: “Ireland belongs to the Irish.”
\u201cAnd the Princess handled it with grace. \ud83d\udc4f\ud83d\udc4f\ud83d\udc4f\n\nKeep Calm\nAnd\nCarry on\n\ud83d\udcaa\u201d

\u201cHow pathetic - it\u2019s fine if you don\u2019t agree with Monarchy but why go out of your way to do this. Perhaps someone needs to tell her that Northern Ireland is part of the United Kingdom.\u201d
The exchange occurred on the city’s Antrim Road after the Prince and Princess of Wales visited the suicide prevention charity Public Initiative for Prevention of Suicide and Self Harm (PIPS), marking their first visit to the country since the death of Queen Elizabeth II.
The couple spoke to staff members about their work assisting people from self-harm and suicide, suicide and even participated in an art therapy session.
