BILLY JOEL - JOEL'S DARK PAST REVEALED IN NEW BOOK

Rocker BILLY JOEL's darkest days are set to be exposed in an explosive new biography, which reveals the longtime boozer was once found passed out in a closet after guzzling furniture polish.

Newlywed Joel, who has just completed a stay at a rehabilitation centre to finally kick his alcohol drink demons, is portrayed as a heavy drinker who once slept with his best friend's wife in HANK BORDOWITZ's BILLY JOEL: THE LIFE + TIMES OF AN ANGRY YOUNG MAN.

A source at publishers BILLBOARD BOOKS says, "The book will recount how Billy moved in with one of his best friends and the friend's wife when he was living in New York.

"When his friend was out of the house, Billy allegedly crawled into the wife's bed."

Bordowitz also reveals, "He (Joel) was known as a blackout drinker, getting so drunk he couldn't remember what he did the night before."
