Elton John's partner David Furnish alluded to Lady GaGa possibly being baby Zachary's godmother in a recent interview.
When asked about the rumors Furnish responded:
"We haven’t publicly confirmed that yet but your sources are very good! I prefer not to comment on it because we are going to make a statement about godparents later on."
Although it's not officially confirmed, it doesn't seem far-fetched. Elton John and GaGa are close friends and Furnish sings her praises as well. You can continue reading the interview at Perez Hilton.
Zachary is one lucky little boy.
