Misbehavin' (1978)

Rita Lawrence, a serial bride and divorcée, throws a party for her most recent divorce -- lucky number thirteen. Watching the proceedings are an angel and a devil, who make a wager over whether lovely Rita’s next marriage will be for love or money. As Rita prowls for her next marital conquest, assisted by her wisecracking gal-pal Gloria Leonard, she must not only juggle three potential suitors, but avoid being assassinated by her vengeful ex-mother-in-law.
