Sir Elton John and David Furnish are planning to have another baby, because they want a sibling for 17-month-old Zachary.
The high-profile couple - who wed in a civil partnership in 2005 - are looking forward to a relaxing summer break and will use the time off to discuss the possibility of having a sibling for 17-month-old Zachary, who was born through a surrogate mother.
David told the Daily Mirror newspaper: ''We are going to take some time this summer and get off the treadmill, have a holiday and talk about the possibility of maybe starting on a second child.
''Nothing has been decided yet. We have to plan it. We're dependent on other people, the egg donor, a surrogate... We have to work together as a team. You can't just snap your fingers and make it happen.''
David, 41, has previously admitted he and Elton think a sibling would be good for Zachary.
He has said: ''I would like Zachary to have a sibling. I think he would be better with a sibling than on his own.''
It seems Elton could use the break he and David have planned as last week the 65-year-old star was admitted to hospital with a respiratory infection, forcing him to cancel some planned concerts in Las Vegas.
