The tender bond between Billy Ray, 45, and Miley isn't just an act on Hannah Montana. In the tween comedy – cable's most-watched series among children 6 to 14 – Miley plays an average kid leading a double life as a pop star and Billy Ray plays her easy-going but watchful father. In real life Billy Ray and his wife, Leticia, 40, are working hard to keep their daughter's life as average as possible as she negotiates the perilous world of teen stardom. Her parents are all too aware of the troubles of young stars such as Lindsay Lohan and Britney Spears. "The biggest phenomenon in all this is that the kid's been able to keep her head on her shoulders," says Billy Ray. "She hasn't flipped out. I'm going to knock on wood." He taps on a nearby wood candleholder. "I pray every day she can stay on that path."

When it comes to her fast-growing fame, it's tough staying a step ahead – even for Billy Ray, whose career is undergoing its own renaissance thanks to his turn this year on Dancing with the Stars. (His next album comes out July 24.) Last month the Cyruses and their five kids had to relocate to a new house (their third in less than two years since moving from Nashville to L.A. ) with a gated entrance because so many young fans rang their doorbell, asking, "Is Hannah Montana home?" Miley's Hannah Montana soundtrack went double platinum last year; her follow-up, Hannah Montana 2/Meet Miley Cyrus, is just hitting stores. She says she now steers clear of movie theaters and amusement parks because the mob scenes "get pretty crazy."

It's a different story at home. "Everything is about keeping her grounded," says Leticia, her mom and manager, who's called "Tish." "She knows that if there was any time I felt like things were getting to be too much for her, we would just not do it." After all, says Tish, behind the blonde wig and glittery eye shadow of Hannah Montana "she's just a kid." Adds Billy Ray: "We try to make it as normal as possible living in this world that she's in."
