So when they broke up in late 2007, Miley was crushed. "At first I bawled for a month straight. I was so sad. I just went into this weird funk. And I dyed my hair black," she says. "When we were dating, Nick wanted me to get highlights -- and so I did that, and I got myself looking great. And then, on the day we broke up, I was like, I want to make my hair black now -- I don't want to look pretty; I want to look hard-core. I was rebelling against everything Nick wanted me to be. And then I was like, I've got to be by myself for now, and just figure out who I really am." And now Miley says she's happily single: "Since [the breakup], I've realized that I've met so many great guys, but I like being the girl nobody can have. No one can touch me, no one's mine. I'm myself. I think it's sexy to do your own thing."

So should we rule out a Miley and Nick reunion? "Maybe he'll be my best friend for the rest of my life or maybe I'll end up marrying Nick Jonas!" she says -- although she might have to fight Selena Gomez for that honor...
