Elton John And David Furnish Expecting Another Baby?

Oooh could there be another celeb baby on the way this year? Apparently Sir Elton John and partner David Furnish are planning a little brother or sister for their 14-month-old son Zachary!

The Mirror reports that Sir Elton is mega keen to become a dad again – and wants to have another baby by the end of this year.

The paper reckons that Elton, 65, and David, 49, will 'ensure the baby has a different biological dad to Zach, so both parties will be blood fathers'.

It reports a source as saying the 'wheels are in motion' adding that David and Elton have 'never hidden their desire to extend their family'.

The couple are now apparently of the belief the 'time is right' for another little one!

The source said: "By the end of this year, or the beginning of next year, there will be a fourth member of the John-Furnish clan. They are incredibly excited and loving every minute of parenthood."

Elton and David - who wed in a civil partnership ceremony in 2005 - became proud parents to Zachary Jackson Levon Furnish-John on Christmas Day, 2010. He was born to a surrogate mum in California, and Elton said at the time he was 'overwhelmed with happiness.'

They have never publicly revealed who is Zachary's biological parent, claiming they do not know, and that they both 'contributed' to the process. Elton has said in the past that he wants his son to know his surrogate mum and for her to be involved in his life, saying she was a 'great woman'.

Elton's spokesperson has kept mum on the latest rumours, saying only 'no comment'.

What do you think? Would two years be just the right age gap between the babies?
