Speaking at a press conference to promote Hannah Montana: The Movie, Cyrus claimed that he is a laid-back dad to the Disney star.
"With Miley, I just trust her so much," he said. "She's got a great head on her shoulders. She makes pretty good decisions most of the time and even has enough common sense that if she makes a bad one she makes adjustments. She knows that's what life is, it's a day-by-day, step-by-step journey."
The actor and singer added: "I try to be a friend for Miley, I know that's not everyone's parenting style. A friend, partner as an actor, a singer, songwriter and let her be a teenage girl and do her thing."
Cyrus also praised his daughter's work ethic, saying: "She's always on. She's funny, she's always writing songs, she's always writing music."
Hannah Montana: The Movie is released in UK cinemas this Friday.
