Carrie Underwood and her husband Mike Fisher have added to their growing family! And no, it’s not their second child yet, but we hear she’s close to her due date. Mike took to Instagram to share a picture of their furry new friend, “Zero”, named by their son Isaiah. Mike joked about the name with the caption. “Meet the newest member of our family! Isaiah affectionately named him Zero. I guess it fits because it’s the chance of surviving if you try to break into our home 😂 #GSD
