London, April 25 (IANS) Singer Elton John has confirmed that his son will undergo a paternity test in a bid to determine whether the singer or his partner David Furnish are his biological father.
The couple welcomed Zachary last year with the help of a surrogate mother. Elton revealed they both contributed sperm samples to the fertilisation process and the two currently don't know which of them is the child's biological father.
"Zach will have to know for his medical records. If it's David, I'd be very proud. It wouldn't matter to me - and vice versa," dailystar.co.uk quoted Elton as saying.
He also revealed that Zachary's surrogate mother sent them breast milk via courier.
"The baby's been brought up in Los Angeles for the first four months so we've had the breast milk 'FedEx-ed' from where she (the surrogate mother) is to Los Angeles every day," he said.
