Elton John and partner keen to have another baby

London, Mar 29 (ANI): Sir Elton John and his long time partner David Furnish are planning another baby by the end of the year, so that their 14-month-old toddler Zachary has a sibling.

According to reports, the pop legend and Furnish will ensure the baby has a different biological dad to Zach, so both parties will be blood fathers.

"The wheels are in motion. David and Elton have never hidden their desire to extend their family, and believe the time is right for another child," the Mirror quoted a source as saying.

"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," the source said.

The couple, who had a civil partnership ceremony in 2005, have been raising toddler Zachary Jackson Levon Furnish-John at their mansion in Windsor, Berks.

Their baby was born to a surrogate mum in California, on Christmas Day 2010. John declared himself "overwhelmed with happiness."

He and Furnish insist they don't know which one of them is Zach's biological father and said "we both contributed" to the process.

"For the time being we don't have a clue who the biological father is. We look at him every day and at the moment he has Elton's nose and my hands," Furnish said.

The two took advantage of surrogacy laws in California that allow a mother to surrender her claims on her newborn, unlike strict rules in the UK. (ANI)
