In January 1934, while Lady Furness was away in New York City, Wallis allegedly became the Prince's mistress.
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 official biographer, he became "slavishly dependent" on her.
According to Wallis, it was during a cruise on Lord Moyne's private yacht Rosaura in August 1934 that she fell in love with Edward.
At an evening party in Buckingham Palace, he introduced her to his mother—his father was outraged, primarily on account of her marital history, as divorced people were generally excluded from court.
Edward showered Wallis with money and jewels, and in February 1935, and again later in the year, he holidayed with her in Europe.
His courtiers became increasingly alarmed as the affair began to interfere with his official duties.

In 1935, the head of the Metropolitan Police Special Branch told the Metropolitan Police Commissioner that Wallis was also having an affair with Guy Marcus Trundle, who was "said to be employed by the Ford Motor Company".
 Claims of an affair were doubted, however, by Captain Val Bailey, who knew Trundle well and whose mother had an affair with Trundle for nearly two decades, and by historian Susan Williams.
