Miley Cyrus is apparently steaming mad over the interview her estranged father Billy Ray gave to GQ in which he said he was "scared" for his 18-year-old daughter and claimed Hannah Montana "destroyed" his family.

"To say Miley is angry is an understatement," a pal blabbed to Popeater. "She's furious that her own flesh and blood would make a private matter so public. Who does he think he is, Michael Lohan?"

Billy Ray reunited with ex-wife Tish at a pet cemetery just a few days ago, but it doesn't sound like he will be seeing his daughter, whom he claims he hasn't spoken to since last year, any time soon after dropping this bomb.

"This isn't what a father does," the 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."

Billy Ray also said in the interview that Miley was surrounding herself by people who are "putting her in danger," and that he should have been a better parent to her.

But the Cyrus source says that Billy Ray's actions are "unforgivable" and that he has still not reached out to his daughter that he feels such fear for.

"Miley has told him that if he wants to talk with her he has her number," says the pal.
