Larry Busacca/Getty Images for EJAFElton John's son Zachary will celebrate his second birthday this coming Christmas, but now reports claim that he may soon have a little brother or sister.

The British tabloid The Sun says that Elton and his partner, David Furnish, are set to become fathers for the second time; the same woman they used as a surrogate for Zachary is reportedly "several months pregnant" with a new baby, due next year.

The couple's staff is said to be sworn to secrecy about the pregnancy, but Elton and David are reportedly "over the moon" about the impending arrival and are already looking for another nanny.  As for the surrogate, a source told the paper, "Elton and David love this lady like a sister and they feel indebted to her for life.  Naturally she has been well rewarded.  But her identity will never be revealed.”

Elton and David have both stated in interviews that they planned to have a second baby because they don't want Zachary to be an only child.
