From the 2001 biography “Madonna” by Andrew Morton, published by St. Martin’s Press.
(from page 70):
(Circa late 1970s, early 80s):
She [Madonna] maintained a determinedly Bohemian lifestyle, a young artist hungrily devouring Hemingway, absorbing Picasso, and savoring Browning – food for the soul, not the body. Nor did the daily cares of makeup, hair-dressers or hot showers concern her.
