Cigarette Girl (1947)

Boy meets Girl. Boy tells Girl he is an oil company president and she tells him she is a popular night club singer. Boy and Girl are telling each other little white lies. But, via some contrived plot complications, Boy becomes a tycoon and the former night club cigarette-selling Girl becomes the Cinderella of Broadway, singing with the Russ Morgan Orchestra. Boy and Girl tell each other they are still more comfortable just being their humble selves. Girl neglects to tell Boy that her singing has been dubbed.
