Jayne Mansfield and Diana Dors (above), playing with Jayne's chihuahuas. The dogs are Momsickle and Popsickle always recognizable as fawn appleheads with thin white lines on their noggins.
Diana had been one of America's best known pin-up models, actress, and sex symbols. Alas like Monroe, Mansfield, and Harlow, the curse of the Blonde Bombshells got her relatively young, of cancer.
So far as I know, Diana never had a chihuahua of her own. But was a definite dog lover, and is shown below at the height of her beauty with one of her pets.
