Meghan Markle acted like a blushing bride when she told a group of schoolchildren and their principal that she was "very, very excited" about her forthcoming wedding.
The American actress' comments came when she met pupils from across Britain after her first Commonwealth Day service at Westminster Abbey.
Hundreds of children were invited to the event, attended by Queen Elizabeth and other royals including Prince William and Kate Middleton, Prince Charles and Camilla, as well as prime minister Theresa May.
In Dean's Yard near the Abbey, Harry and Meghan chatted with the youngsters who earlier had been in the congregation, and Holly Hartley, principal of Thistley Hough Academy in Stoke-on-Trent, and her pupils.
"She was saying what a lovely service it had been and her first service at Westminster Abbey," said Ms Hartley.
"We congratulated her on her engagement.
"She was delighted and said she was 'very, very excited' - she stayed chatting with us for quite a while. What a lovely, lovely lady."
Harry and Meghan will wed on May 19 in St George's Chapel, Windsor Castle.
The couple have invited 1,200 members of the public, who will be chosen by lord lieutenants across Britain, into the grounds to celebrate their big day.
"She said what a lovely day she'd had and we had a little joke about the rain, as we had to brave the rain earlier," Ms Hartley added.
"She said it was great to see people from all over the world so well represented at the service."
