Miley Cyrus, aka Hannah Montana, has now been linked romantically to “Nashville Star” contestant Justin Gaston, and if the tabloids are right, Gaston is living at the Cyrus family home so father Billy Ray Cyrus can keep an eye on the two.The 15-year-old Cyrus, who turns 16 on November 23, didn’t confirm one way or another whether she’s actually dating Gaston, who is 20, but told Ryan Seacrest on his KIIS-FM radio show that she’s not worrying about the age difference, adding, “Everyone started judging us as soon as we started hanging out.” But are they dating? “Maybe, maybe not.” She did say of Gaston, who in addition to being an aspiring music artist is also an underwear model, “He’s a really great Christian guy, which is awesome.”Golly gee, what a dream boat.Miley Cyrus was linked romantically last year to tour mate and youngest Jonas Brother, Nick Jonas, and until recently was the undisputed Queen of Squeaky Clean. Then came the Vanity Fair pics and now her maybe-boyfriend residing under her own roof.Does any of that change her image as the Kid-Safe Pop Princess? And who is Justin Gaston, anyway? I thought everyone on “Nashville Star” was so woefully untalented I only made it through one episode (and I love those kind of shows). But here, you judge for yourself. And if nothing else, the publicity Gaston gets from his possible romance with Miley Cyrus will be good for his career. Maybe he’ll be the opening act on her next world tour, and she can do for him what she did for the JoBros.
