Britain's Peter Phillips and new wife Autumn Kelly controlled which of their wedding photos appeared in celebrity gossip magazine Hello!
Prince Harry was said to be "incensed" that private photographs of him and his girlfriend, Chelsea Davy, featured in the magazine's spread.
A royal source said: "If Peter and Autumn had picture approval, this really will be embarrassing. In effect it would mean they allowed shots of Peter's cousin and his girlfriend to be used, despite the sensitivities. At best they were extremely naive."
Harry's 25-year-old brother William - who was not at the nuptials - is also said to be angry about the photos of his girlfriend Kate Middleton at the ceremony in Windsor's St. George's Chapel and subsequent reception at the nearby Frogmore House appearing in the magazine.
The source said: "The princes have battled to protect their girlfriend's privacy."
