When asked in an interview, "Correct me if I'm wrong but Lady Gaga has been named Zachary's godmother. What led you to choose her?" Furnish replies, "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."
In other words, it's not a confirmation but it's certainly not a denial.
In the interview with Macleans, a Canadian magazine, Furnish talks about how Canadians and Americans view sexuality and equal rights differently.
Furnish, a Canadian, says, "I do feel Canada is much more progressive and more accepting on all sorts of levels relating to same-sex couples and families."
He says that Lady Gaga embodies an attitude that he'd like around his family, telling Maclean's, "She's" all about inclusiveness and tolerance. She believes that you can be whoever you want to be and that we don't have to live in a world of conformity and that we can all [benefit] from individuality. That's the best message in the world. The freedom to be who you are, do what you want and love who you want to love."
