The Girl Can't Help It is a 1956 American musical comedy film starring Jayne Mansfield in the lead role, Tom Ewell, Edmond O'Brien, Henry Jones, and Julie London. The picture was produced and directed by Frank Tashlin, with a screenplay adapted by Tashlin and Herbert Baker from an uncredited 1955 short story by Garson Kanin, "Do Re Mi". Filmed in DeLuxe Color, the production was originally intended as a vehicle for the American sex symbol Jayne Mansfield, with a satirical subplot involving teenagers and rock 'n' roll music. The unintended result has been called the "most potent" celebration of rock music ever captured on film.

The original music score, including the title song performed by Little Richard, was by Bobby Troup, with an additional credit to Ray Anthony for the tune "Big Band Boogie".

A slot machine mobster, Marty "Fats" Murdock, wants his blonde girlfriend, Jerri Jordan, to be a singing star, despite her seeming lack of talent. He hires alcoholic press agent Tom Miller to promote Jordan, both because of his past success with the career of singer Julie London and because he never makes sexual advances towards his female clients.

Miller sets to work by showing Jordan off around numerous night spots; his machinations arouse interest in Jordan and soon offers of contracts follow.

Miller whenever he hears Julie London he would imagine her there. Circumstances change and he starts imagining that Jerri is there instead of Julie.

Miller tells Murdock that all Jordan really just wants to be a homemaker and tries to persuade Murdock not to push Jordan into a show-business career. When he tells Murdock that Jordan's singing is so bad it shatters light bulbs, Murdock insists on having Jordan record a song he composed while in prison, "Rock Around the Rock Pile" (a parody of "Rock Around the Clock"). Miller reluctantly records Jordan performing the part of a prison siren in Murdock's song and heads to Chicago to promote it to Wheeler, a former mob rival of Murdock who now has a monopoly over the jukebox industry.

Suspicious of Miller's reluctance to promote Jordan and of the obvious attraction between Miller and Jordan, Murdock has his associate Mousie wiretap a phone call between the pair. Feeling pity for them, Mousie edits out the romantic portions of their conversations and convinces Murdock that their relationship is strictly business.

In Chicago, Wheeler is impressed by the song and Jordan's voice and offers to sign both Jordan and the songwriter. However, when Miller reveals that the songwriter is Murdock, Wheeler refuses to promote the song. A furious Murdock bullies bar owners into buying jukeboxes from him instead and successfully promotes his and Jordan's song. To prevent Murdock from stealing his business, Wheeler arranges to have Murdock assassinated at the rock show where Jordan will be making her debut.
