Miley Is Steaming Mad About Billy Ray's Betrayal

Miley Cyrus is furious that her country singin' daddy, Billy Ray, sat down with GQ to bash the Disney show that made them mega-rich, as well as for his comments saying he's "scared" for his daughter's well-being.

Now, I'm hearing that the 'Hannah Montana' star has signaled that she wants him to clam up and stop acting like another infamous stage dad.

"To say Miley is angry is an understatement," a friend of the Disney star tells me. "She's furious that her own flesh and blood would make a private matter so public. Who does he think he is, Michael Lohan?"

In GQ, Billy Ray said, "The damn show ['Hannah Montana'] destroyed my family" and he would "erase it all in a second if I could."

He also dipped into personal matters by claiming, "She's got a lot of people around her that's putting her in a great deal of danger. I know she's 18, but I still feel like as her daddy I'd like to try to help. Take care of her just a little bit, to at least get her out of danger."

While Miley hasn't commented publicly about the article, friends tell me the actress-singer is mystified, saying it's "unforgivable" that Billy Ray would randomly start biting the hand that fed him, as well as gab about his kid's personal life.

"This isn't what a father does," my source says. "He never said a bad world about 'Hannah Montana' all those years it made millions for the family, and now that Miley has turned 18 and is making her own decisions, he does this. Unforgivable."

There have also been rumblings that Miley and Billy Ray haven't actually spoken since December, before his interview for the GQ article. "Miley has told him that if he wants to talk with her he has her number," the friend reveals. "It's been the same number she always has had."
