Koo—she managed to master only one Chinese phrase: "Boy, pass me the champagne". By September 1925, she and her husband were back in the United States, though living apart. Their divorce was finalized on December 10, 1927. Second marriage By the time her marriage to Spencer was dissolved, Wallis had become involved with Ernest Aldrich Simpson, an Anglo-American shipping executive and former officer in the Coldstream Guards. He divorced his first wife, Dorothea (by whom he had a daughter, Audrey), to marry Wallis on July 21, 1928, at the Register Office in Chelsea, London. Wallis had telegraphed her acceptance of his proposal from Cannes, where she was staying with her friends, Mr. and Mrs. Rogers.

Edward denied this to his father, despite his staff seeing them in bed together as well as "evidence of a physical sexual act". Wallis soon ousted Lady Furness, and the Prince distanced himself from a former lover and confidante, the Anglo-American textile heiress Freda Dudley Ward. By the end of 1934, Edward was irretrievably besotted with Wallis, finding her domineering manner and abrasive irreverence toward his position appealing; in the words of his
