Elton, 65, and David Furnish, 50, are thought to be using the surrogate who gave birth to son Zachary — now 23 months old.
Elton was “over the moon” last night.
A surrogate for the Rocket Man singer and hubby David is due to give birth next year, The Sun can exclusively reveal.
Last night a source close to the pair said: “Elton and David love this lady like a sister and they feel indebted to her for life.
“Naturally she has been well rewarded. But her identity will never be revealed.”
The mum — believed to have been recruited via the Center for Surrogate Parenting in Encino, California — is said to be already “several months” pregnant.
Zachary will have turned two by the time his sibling arrives. He was born on Christmas Day 2010.
He said: “At what stage we don’t know. But we definitely will. I don’t want him to be an only child.”
Yesterday excited Elton kept his nappy news to himself as he landed in Australia for a sell-out tour.
Furnish — 50 last month — will tonight be at a glittering bash at London’s iconic Battersea Power station.
He and Hollywood’s Kevin Spacey are co-hosting the annual Winter Ball — which raises money for the Elton John Aids Foundation.
Furnish will then jet out to join his husband.
Last night Elton’s agent refused to comment.
