Kahlo’s amorous relationship with her husband is also vividly described throughout Weatherwax’s texts. He wrote of them:
They seem to be completely happy. She in her twenties, he in his forties. She a German-Mexican, he ever so typically Mexican. He gets up... putting an arm around the Queen. He bends down to her. His lips move out, making a delicate little noise. The Queen laughs, hugs him, and kisses him on the neck. Don Diego straightens up, slowly. The Queen is still clinging to him, her feet now twelve inches from the floor. She bites his ear, laughs, and lets go. Arm in arm they turn the end of the corridor, unlock another door, and enter the Royal Studio.
Weatherwax also provides details about Kahlo’s portrait painting:
The Queen is already hard at work. The poser doesn't crack a smile, doesn't even look up when the door opens. Frieda works like lightning. She has done many oils. If she wished, she could have a one-man exhibit in New York at any time... At last Don Diego comes home... The Queen throws her arms around his neck, laughing gleefully. Astonishment, fear and joy struggle in Don Diego's face. The poser bows good-bye. The King and the Queen go to Frieda's gigantic easel. Don Diego looks long and soberly at his wife's work. 'Bueno', he says. After a while he adds in Spanish, “A pure and strong woman's spirit is as precious as the light of the stars.’
