April in Paris (1952)

Miss Ethel 'Dynamite' Jackson is a chorus girl who mistakenly receives an invitation from the State Department to represent the American theatre at an arts exposition in Paris, France. There's only one problem: the invitation was meant for Miss Ethel Barrymore. Meanwhile, S. Winthrop Putnam, the bureaucrat who made the mistake, tries unsuccessfully to correct his mix-up. It's too late, for Dynamite Jackson is off to Paris, where the two meet and marry, or so they think.
