Giscard d'Estaing wrote his second romantic novel, published on 1 October 2009 in France, titled "The Princess and the President". It tells the story of a French leader having a romantic affair with a character called Patricia, Princess of Cardiff. This caused many rumours that the book was based on a real-life affair between Giscard d'Estaing and Diana, Princess of Wales. He later said that such an affair never happened and that the book was fictional.
