Singer from "The Other Girl in His Life" story in romance comic book Love at First Sight #10 (July 1951).
A small town wanna-be struggling in the big city, she gets her big break when she's hired by famous band leader Hal Drake, over the objections of members of his own band. He grooms her, trains her, gives her a makeover, and soon those band members are eating crow.
But when Hal sort-of-proposes to her, it comes out as just an ugly way to spite his former singer and girlfriend who jilted him, Rosamond Farling.
But Jerome agrees to get married because she really loves Hal. But when Rosamond comes back, she thinks she's lost Hal to her, but Hal comes back to Jerome even harder.
