Sir Elton John is the ''happiest'' he has ever been.
The 'I'm Still Standing' singer - who has 20-month-old son Zachary with his long-term partner David Furnish - admits his 19-year-relationship with the Canadian filmmaker, his family life and his charity work have made him happier than at any time previously.
The 65-year-old singer and his husband David Furnish became parents to Zachary Levi on December 25 2010 via a surrogate mother and while he is loving fatherhood, Elton wishes they had decided to start a family sooner.
Sir Elton John always thought his homosexuality was ''common knowledge''.
The 65-year-old singer - who said he was bisexual in 1976 and married Renate Blauel in 1984, before confirming he was gay in 1988 - says he was ''waiting'' to be asked about his sexual preferences as it was never something he kept secret.
