Brooklyn native Barry, whose birth name was Barry Alan Pincus, was also once married to a woman.

In his 1987 autobiography Sweet Life, he makes a fleeting reference to falling in love with his high school sweetheart.

Her name was Susan Deixler and they married in a civil ceremony followed by a Jewish wedding in front of a Rabbi.

But less than a year later, Barry, who was 21, apparently decided he was too young to be tied down and moved out of their apartment and out of the marriage in order to focus on his music career.

Susan responded by seeking an annulment of their marriage, which legally meant it had never happened.

Barry fiercely guards his private life and when he's not on the road, these days he retreats behind the gatesof his 64-acre Palm Springs hideway.

He has never publicly spoken about his sexuality although he has been the subject of rumors over the years.

'I am a private guy,' the superstar said in a 2012 interview with UK newspaper The Telegraph.

'You can only come into my world if I invite you in. From the very beginning that was the rule. I learnt how to deal with the publicity/press thing. You just say, ‘I’m not interested in talking about [that],' he said. 'That’s the only way I can survive...... I don’t want strangers knowing everything. If that happened, that would drive me crazy.”
