Explaining in an interview with People Now, Billy-Ray revealed that, "Hannah Montana was originally written about Kylie, and... up until the day we starting filming the pilot, it was still Kylie. But I kept saying 'Miley'."
He added, "By the third time into it somebody stopped and said 'Wait a minute, everybody, script change... Kylie is now Miley.'"
Lol.
Dads, amiright?
