She sings on the show, but sees Ward is clowning around behind her, making the act a comedy. Humiliated, she storms off the set, refusing to see him again.
When she finds out later his show is about to be cancelled, that her number was the hit of the show, and that Ward didn't tell her what he was going to do so the act would be funnier, she has a change of heart, comes back on his show and saves it. They reconcile and marry.
Not to be confused with similarly named singer Miss Stardust, from an earlier issue of the same comic book.
