Congratulations are in order for Sir Elton John and husband David Furnish. Sun magazine is reporting that the couple will soon welcome a new addition to their family, giving son Zachary a little brother or sister via surrogate. “Elton and David love this lady like a sister and they feel indebted to her for life,” a source close to the couple is quoted as saying. “Naturally she has been well-rewarded. But her identity will never be revealed.” The mystery lady is already several months along and will give birth early next year.
