After her divorce from Randolph Churchill, she moved to Paris and in 1948 began her five-year-long affair with Agnelli. She described this as the happiest period of her life. Agnelli, however, was not faithful in this relationship. In 1952, Pamela found him with a young woman, Anne-Marie d'Estainville, and complained strongly about this, despite her own past behaviour. Agnelli sustained a severe leg injury in a car accident while bringing d'Estainville home. Pamela nursed him through his injury, and later became pregnant (although it was never confirmed that this was by Agnelli), but had an abortion in Switzerland. Later, Princess Marella Caracciolo di Castagneto became pregnant by Agnelli, and Pamela Churchill ended the affair.
