(QUEBEC CITY, Canada) -- Could the pitter-patter of little feet be in the future for royal newlyweds Prince William and Kate Middleton?
Perhaps not quite yet, but as the Duke and Duchess of Cambridge interacted with fans in Quebec City, Canada, Sunday as part of their North American tour, one fan wished Kate well in starting a family. Kate, 29, who has not spoken publicly about children, was overheard saying, "Yes, I hope to."
"It was really quite a surprise to hear her say that, quite an emotional response," said Katie Nicholl, an ABC News contributor and author of The Making of a Royal Romance. "For Kate to give such an intimate aspiration is very special.
"You look at the two of them. It's the chemistry, the love between them. It won't be long before they will," she added.
The moment happened when two little girls went up to the royal couple to give them flowers. The father of one of the little girls, David Cheater, was the fan who received Kate's unexpected response.
"It was privilege, a real privilege," Cheater said, holding 2-year-old daughter Raffaella.
The royal couple continues their 11-day tour on Monday in Prince Edward Island, Canada, the fifth day of the tour, where William, who is a military helicopter pilot, will be doing a flying demonstration in which he makes an emergency landing on Dalvay Lake.
While touring Quebec City Sunday, Prince William, 29, spoke to Canadians in their native tongue -- French -- and even apologized for his accent.
It's their first overseas trip as a married couple and everywhere they go, the prince and his bride have been greeted by fanfare.
But while more than 1,000 fans gathered to watch their tour of the city, the couple encountered about 200 protesters. French-speaking separatists have sprung up throughout the tour, but have caused little disruption.
ABC News contributor and Sun editor, Duncan Larcombe, says that while British royals often encounter protesters when they come to this part of Canada but, nonetheless, William and Kate have viewed this trip as a success.
"There have been some demonstrations, some protests, but nothing too serious," Lacrombe said.
