Sir Elton John and David Furnish are hoping to father a second child this summer
David, 49, has revealed he and the `Rocket Man` hitmaker would like to give one-year-old son Zachary a little brother or sister, and are thinking about enlisting the help of a surrogate once more. He said: "I would like Zachary to have a sibling. I think he would be better with a sibling than on his own. It`s something we talk about all the time. But in terms of when, where and how, nothing`s decided yet.
"I think we are going to wait till thissummer. Our life is always like a treadmill with Elton constantly working and touring. But when we go away to our house in France, that`s when we sit back and go [big exhalation] okay, how is this working, how are you feeling?"
The couple - who met in 1993 and became civil partners in 2005 - both donated sperm the first time around so they don`t know which one is the father, and plan to do the same again.
Explaining the process, he told the London Evening Standard newspaper: "We could go back to the same egg donor, so biologically there would certainly be a connection between brother and brother or brother and sister."
However, they may need to use a new surrogate mother because their previous one, "has been a surrogate before but has a life of her own and her own family.
"It`s a big commitment to make, nine months of their life that doesn`t just affect them but their children, their husband, their partner. If we found a surrogate who is half as beautiful as our first, we would be very lucky."
