The Prince of Wales was described as "gorgeous" by a woman during a visit to Cumbria.
Prince Charles admitted he was "flattered" by the compliment when he met young farmers and volunteers.
A spokeswoman for the Palace said the woman shouted out: "We think you're gorgeous, Charles."
The Prince replied: "Flattery will get you everywhere," the spokeswoman added.
Prince Charles was in Cumbria to launch a pilot scheme to encourage tourists to donate to The Prince's Countryside Fund, which helps people in rural areas.
