This and several other details about Bowie, the British singer-songwriter who died after an 18-month battle with cancer on January 10, find mention in a new book named "Bowie: The Biography" by Wendy Leigh.
In the biography, published by Simon & Schuster imprint Gallery Books, Leigh reveals the man behind Bowie's myriad images - up to and including his role as stay-at-home dad, happily monogamous in his quarter-of-a-century-plus marriage to supermodel Iman.
Said David once, "She never let me forget it. She was enthralled by the idea."
David himself was not immune to the significance of sharing a birthday with Elvis, and it added to his sense of his own destiny, his own specialness. Consequently, when he watched his aunt Una's daughter, his cousin, Kristina, dance to "Hound Dog" soon after it was released in 1956, his passion for music was ignited.

Leigh says even when Bowie was on the threshold of stardom, Elvis continued to exercise such a sway over him that, in the face of the King, he would instantly be reduced to the level of fandom.
"In June 1972, David and his guitarist Mick Ronson took a midday flight from Heathrow to New York and arrived just in time to catch Elvis headlining Madison Square Garden. Or so they hoped. In fact, they arrived there after the show had begun.
David later it was "really humiliating but unmissable".
The author brings fresh insights to Bowie's battles with addiction; his insatiable sex life - from self-avowed gay to bisexual to resolutely heterosexual - and countless conquests; his childhood in a working-class London neighbourhood and the troubling family influences that fuelled his relentless pursuit of success; and much more.
"Neither age, race, religion, nor the looks of his lovers ever prevented him from following the siren's song of his lust, wherever it might lure him," she writes.
Long after David's birth at 40 Stansfield Road, a three-story terraced house, mythology had it that the midwife who delivered him swooned about his "knowing eyes" and insisted that the newborn baby had "been here before", says Leigh.
From his father, David got his love of reading; he got his first taste of Hemingway from his father's readers' book club, which sent him a book a month, each of which David eagerly devoured.
Another, less salutary habit that David picked up from his father was chain-smoking, and despite undergoing hypnosis and aversion therapy to break the habit, for a great part of his life, he was unable to quit, says Leigh.
