SIR ELTON JOHN and "hubby" DAVID FURNISH have become DADS - as it yesterday emerged a surrogate mum bore them a baby on Christmas Day.
The healthy boy - named Zachary Jackson Levon Furnish-John - was born weighing 7lb 15oz in California.
Last night celebs flocked to congratulate the new parents - as rock legend Sir Elton declared himself "overwhelmed with happiness" to become a dad at 63.
It was not revealed who the biological father was. The identity of the surrogate mum was also being kept a closely-guarded secret.
Sir Elton and Furnish, 48 - who "wed" in a 2005 civil partnership - were last night in America preparing to jet home to the UK with their new son.
They said in a joint statement: "Zachary is healthy and doing really well, and we are very proud and happy parents."
Last night a friend of Furnish told The Sun: "Both are thrilled but it is Elton in particular who is overwhelmed with joy."Zach is now Sir Elton's life. This means there is now an heir to his throne, his millions and his legacy.
Anyone who thinks that he won't change nappies and getting up in the night is wrong. His new focus is family life with David and their son.
