“It was all in the same moment. My point is we weren't allowed to tell our story because they didn't allow it."
Harry, who also appeared in the clip of Meghan talking about their engagement interview, then made a joke about how the couple had never been allowed to tell their story - to which Meghan laughed and said “that’s true”.
Mishal later spoke to Saga Magazine about Meghan's comments, telling the publication: "What I remember about that day was two people who were excited about their engagement and in love. They seemed to have thought through what their new lives would be like and what marriage would mean for her life in particular.
"There was nothing that pointed to what would happen. It was two people who were full of joy in each other and life."
Both Harry and Meghan previously revealed that their engagement took place at their home Nottingham Cottage.
Describing the moment as "romantic", Meghan shared that she kept butting in during the proposal to try and say yes before he had even finished asking the big question.
The couple - now parents to Prince Archie, six, and three-year-old Princess Lilibet - celebrated their seventh wedding anniversary earlier this month.
