Everyone's been talking about the difference between 15-year-old Miley Cyrus and her new 20-year-old BF Justin Gaston. But Miley says age ain't nothin' but a number to her. "After my last two years, there's been a lot of things that happened, so I've learned just not to judge anyone and go into our friendship with an open mind and not really worry about the age or anything," she says. Yes, she said "friendship" -- while she won't confirm she's dating him, she has no problem with gushing about him. "He's a really great Christian guy. He's gone through stuff, and I've gone through stuff, and everyone goes through that," she says. "I think it's really awesome that we have that in common -- that we can talk about it and that we can understand [each other] ... he gets it."

And so for now, thing are really good between Miley and Justin. "We're just really happy with everything and the way everything has worked out," she says, adding that, "Our families are like, 'Whatever happens, happens.' If he's nothing but a really good friend, that's awesome. More than anything, he's really helped me move on from a lot of things." Like a certain Jonas Brother?
