To initiate the visit - and the pair's first overseas engagement as a married couple - Prince Harry gave a four-minute speech at Glencairn in Sandyford remarking on the unique relationship between the United Kingdom and Ireland.
"Meghan invests more energy and flaunts her proactive compassion more than Harry", she said.
Harry and his American wife Meghan began a two-day visit to the Irish capital on Tuesday, their first trip overseas since their wedding in May.
"A pleasure to meet Prince Harry & the Duchess of Sussex at the British Ambassador's Residence this evening". British troops opened fire on a crowd there almost a century ago, on a day known as Bloody Sunday during Ireland's War of Independence.
Noone was quick to backtrack on her tweet as many pointed out members of the royal family are required to refrain from making political statements.
Harry and Meghan visit Croke Park, home of Ireland's largest sporting organization, the Gaelic Athletic Association.
Earlier in the day, the Duke and Duchess of Sussex had an adorable run in with an Irish toddler.
Harry grimaced in mock pain and told the four-year-old: "You might have a beard soon, you never know". The happy couple said their own vows as Rachel walked up the aisle with her dad to John Legend's All Of Me. Meghan paired the look with Paul Andrew heels in black suede, diamond earrings from Birks, and a sleek, center-parted bun.
Fire or no fire, Meghan is giving everyone something to talk about with her Ireland trip.
