You may want to hold off on buying that bottle of Chanel Number 5: a new book claims that Coco Chanel - fashion guru and inventor of the little black dress – may have been an anti-Semite and Nazi collaborator during World War II.

In "Sleeping with the Enemy: Coco Chanel's Secret War," Hal Vaughan explores the designer's "long-whispered collaboration" with the Nazis, including her membership and activities for the Abwehr Nazi military intelligence. According to Vaughan, Chanel's lover during the war, Baron Hans Gunther von Dincklage, was a Nazi agent.

According to the book, the baron appeared to be "an innocuous, English-speaking tennis player, playboy, and harmless dupe," but was in fact a Nazi agent who was honored by Hilter and Goebbels during the war.

Chanel, who the book claims was “fiercely anti-Semitic long before it became a question of pleasing the Germans," was not the only French artist to allegedly collaborate with the Nazis. Among others, Jean Cocteau and Maurice Chevalier were also said to have worked with the Nazis.
