Jerri Jordan

From the 1956 comedy film The Girl Can't Help It. Mobbed up slot machine magnate Fats O'Murdock (Edmond O'Brien) hires on-the-skids agent Tom Miller (Tom Ewell) to make his ditzy, talentless girlfriend Jerri Jordan (Jayne Mansfield) a singing star.

Miller gets her to record "Rock Around the Rock Pile," backed up by Ray Anthony and his band, where all she has to do is scream on cue. Later, it turns out she can sing, but she just wants to be a mother and wife, not a star, and she ends up with Miller.
