Singer Sir Elton John and his partner David Furnish welcomed a baby boy on Christmas, Us magazine reported.

Zachary Jackson Levon Furnish-John was born in California via a surrogate. He weighed 7 pounds, 15 ounces and measured 22 inches long.

In a statement, the couple said they were “overwhelmed with happiness and joy at this very special moment.”

The couple attempted to adopt a young Ukrainian boy last year, but authorities in the Ukraine didn't approve.

Sir Elton, 63, and Furnish, a 48-year-old filmmaker, entered a UK civil partnership in 2005 after a 12-year engagement.

Sir Elton was blasted last year for performing at the wedding of conservative radio host Rush Limbaugh. Limbaugh went on to say that Sir Elton is not a supporter of gay marriage. But the singer-songwriter will be performing next month at a fundraiser for the American Foundation for Equal Rights (AFER), a group formed specifically to support a challenge to California's gay marriage ban, Proposition 8.

The couple added in their joint statement that “Zachary is healthy and doing really well, and we are very proud and happy parents.”
