Miley Cyrus has opened up about the complicated relationship she has with her dad, Billy Ray Cyrus. During an interview with David Letterman for the newest episode of his Netflix series My Next Guest Needs No Introduction, David inquired about the rumored rifts. "There's not estrangement here with your father," he said, "it's just the way things are played?" "Yeah," Miley said. "I think, what is so beautiful is that my parents, they served their children, and I know this. My parents served us and sacrificed so much for us. Anything we dreamed of, they made possible."
