In an incident around 1788, Louis Philippe II, Duke of Orléans, presented Duthé to his fifteen-year-old son Philippe (later King Louis Philippe I) to "learn some facts of life." When she was later seen in Philippe's royal carriage on the Champs-Élysées, some young aristocrats took offense, as normally only princes rode in royal carriages; they sang a song set to a popular tune using the lyrics "La Duthé a dû téter", roughly translated as "La Duthé must have suckled royally."
