Billy Ray Cyrus probably could have come up with a better way to communicate his concerns about daughter Miley other than belly-aching about them to GQ. And now comes word that his famous offspring is ticked about his candid sit-down, during which he expressed his belief that the Cyrus clan is under attack by Satan, who apparently has nothing better to do these days than tempt 18-year-old starlets with a bong full of Salvia.

"To say Miley is angry is an understatement," a pal tells 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?"

In addition to Lucifer's evil ways, Billy Ray blames "Hannah Montana," the show that made Miley a star and provided him with a paycheck in those lean, post-"Achy Breaky" years, for destroying their family (he and wife Tish filed for divorce in October).

"This isn't what a father does," fumes the insider. "He never said a bad word 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."

According to the source, father and daughter are currently in a conversational standoff, but, "Miley has told him that if he wants to talk with her he has her number."

Someone else who supposedly has her number: John Mayer, or so says the latest issue of Star, which claims it was a daddy-issue-extravaganza over Grammy weekend as the ookily age-mismatched pair supposedly "got touchy-feely."

At Clive Davis' star-packed pre-Grammy bash, "She followed John around all night like a puppy dog," maintains an eyewitness. "She put her arm around his waist, and even grabbed his behind."

Excuse us for a sec. We know we left that extra-strength brain bleach around here somewhere …

The tab says things took an even squickier turn backstage at the Grammy Awards, when the 33-year-old crooner-turned-Johnny Depp DNA snatcher "leaned over and kissed" Miley, who, we feel the need to point out, is an entire high school sophomore younger than he is.

"It was quick and intense and a bit shocking," says a spy, "but it also seemed sweet."

Oh, if only the story stopped there. No such luck: "Afterward, Miley slapped his butt and told him, 'You rock!'"

And despite the crooner's reputation for hitting on any female with opposable thumbs (and purportedly stomping on young hearts like Taylor Swift's), "[Miley] believes she can make John a one-woman man," according to the tab. "She thinks they are great together because she's as wild as he is."

But before you begin rending your garments and tearing out your hair as you agree with Billy Ray that this must surely be the devil's work, keep in mind that a Miley insider assures Gossip Cop that the hookup whispers are "not true," and she only said "hello in passing" to John at the Clive Davis shindig.

Not that she would necessarily mind Mayer's attention. The popster, who was recently seen snuggling with her "So Undercover" co-star (and Amy Winehouse ex) Josh Bowman, gushed about him in July 2009.

"Dear GOD, I would like a boy that is like John Mayer/ James Morrison/ Elvis/ Rob Thomas all in one," she wrote on her now-defunct Twitter. "You're the best!"
