Photos have also emerged of the Duchess touching her stomach after the royal couple met locals in Seymour Square, Blenheim.
This photo of the Duchess of Cambridge has sparked pregnancy rumours.
There have been previous reports that Prince William and his wife are expecting their second child, but the Duke of Cambridge played down speculation last month, saying that one child was enough at the moment.
There’s no doubt the world would welcome the announcement of a sibling for eight-month-old Prince George.
