La Scandaleuse Ingénue (titre original : The Petty Girl) est un film américain réalisé par Henry Levin, sorti en 1950.
In New York City, George Petty (Robert Cummings) tries to convince car manufacturer B. J. Manton to use pretty women to help advertise his dreary new car model. He is not succeeding when Manton's daughter, the often-married Mrs. Connie Manton Dezlow (Audrey Long), interrupts the business meeting, takes a liking to the handsome young artist, and makes herself his patron. Soon, she has furnished him with a lavish apartment, complete with a butler named Beardsley (Melville Cooper). She also talks him into abandoning his cheesecake paintings in favor of more respectable portraits.
