Elton John is identified as the biological father on the birth certificate of his newborn son, Zachary, reports website Pop Eater.

"Elton really wanted the child to have his genes," a friend of John and partner David Furnish reveals to the website. "He has a God-given talent and wanted to pass that on to a child. And after years of discussion and thought, Elton and David decided together that Elton's sperm would be used."

The source also reveals that "Elton has already purchased a $2 million adjoining apartment in Los Angeles to turn into the perfect nursery. Elton's son already has four round-the-clock nannies and his own chef."
