Born in London to two American parents, the glamorous actor, philanthropist and oft-married beauty relinquished her U.S citizenship twice. In 1965 at the U.S. Embassy in Paris, she made a half-hearted effort, deleting the phrase “abjure all allegiance and fidelity to the U.S.” When the State Dept. declared that invalid, she applied again at the U.S. Embassy in Rome and this time let the wording stand. When she married John Warner, the former Secretary of the Navy who would later become a Senator, she applied to reinstate her U.S. citizenship.
