Billy Joel - Joel Plans Autobiography

BILLY JOEL is to lay bare his biggest secrets in a new tell-all book - he is writing his autobiography.

The Piano Man has signed a $2.25 million (£1.5 million) deal with publishing giants HarperCollins for the tome, which is expected to include details of his turbulent life.

Joel has gone through a divorce to wife of five years, Katie Lee, and toured with Sir Elton John in the last year (08-09) alone.

He's also dated a string of beautiful women, including a marriage to model Christie Brinkley and an alleged relationship with Elle MACpherson in the 1980s.

His first marriage was to his business manager, Elizabeth, with whom he had an affair while she was married to his then music partner, Jon Small.

The singer has also battled depression, spent time on suicide watch in hospital, and has undergone treatment for substance abuse.

A source tells Britain's Daily Express, "Billy's life could be a movie. His early days in the Bronx where he was teased because he played piano led him to take up boxing. He has battled with depression and left a suicide note which became the lyrics to Tomorrow Is Today. He has also been in rehab. Then there's his love life. He has dated and married some of the most beautiful women in the world."
