The piano man and his husband, David Furnish, have become parents to a 7-pound, 15-ounce baby boy born on Christmas Day.
The news was first reported by USMagazine.com and it was confirmed to The Associated Press by John's Los Angeles-based publicist.
Zachary Jackson Levon Furnish-John was born in California via a surrogate, whose identity is being protected by the new parents.
Zachary is 62-year-old John's first child with the 48-year-old Furnish. The couple married in 2005.
In a joint statement, the new parents told USMagazine.com that "Zachary is healthy and doing well" and they were "overwhelmed with happiness and joy at this very special moment."
