Elton John and David Furnish have announced the arrival of their second child, a boy called Elijah Joseph Daniel Furnish-John.
The baby was born in Las Vegas last Friday via a surrogate mother and the couple have spoken about their happiness in an interview with Hello! magazine.
"We are just overwhelmed with happiness and excitement," Elton said. "Both of us have longed to have children, but the reality that we now have two sons is almost unbelievable.
"The birth of our second son completes our family in a most precious and perfect way. It is difficult to fully express how we are feeling at this time; we are just overwhelmed with happiness and excitement."
Elton, 65, and David, 50, are believed to have used the same California-based surrogate who carried their first son Zachary, now two.
The identity of the surrogate has never been revealed, and friends say they will keep her name secret forever.
"Elton and David love this lady like a sister and they feel indebted to her for life," a source said shortly Zachary's birth.
"Naturally she has been well rewarded. But her identity will never be revealed."
Zachary and Elijah are believed to have been conceived using the surrogate's egg, and a mixture of Elton and David's sperm.
