<P> The song is perhaps most famously performed by Marilyn Monroe in the 1953 film Gentlemen Prefer Blondes . Monroe 's character , Lorelei Lee , has been followed on a Transatlantic ocean liner by a detective hired by her fiancé 's father , who wants assurance that she is not marrying purely for money . He is informed of compromising pictures taken with a British diamond mine owner and cancels her letter of credit before she arrives in France , requiring her to work in a nightclub to survive . Her fiancé arrives at the cabaret to see her perform this song , about exploiting men for riches . Diamonds are an element in another story line in the film , in which Lorelei is given a diamond tiara by the mine owner , in gratitude for her recovering the photographs . In a later scene , Jane Russell , who played opposite Monroe , sang `` Diamonds Are a Girl 's Best Friend '' in court , while pretending to be Lorelei . </P>
