Miley Cyrus has finally admitted that she dated teen rocker Nick Jonas, saying they were "in love."

"We became boyfriend and girlfriend the day we met," Cyrus, 15, says in the September issue of Seventeen magazine. "He was on a quest to meet me, and he was like, 'I think you're beautiful and I really like you.' And I was like, 'Oh, my gosh, I like you so much.'"

She adds that she and 15-year-old Nick "loved each other."

"We still do, but we were in love with each other," she tells Seventeen. "For two years he was basically my 24/7. But it was really hard to keep it from people. We were arguing a lot, and it really wasn't fun."

After they broke up at the end of 2007, Cyrus tells Seventeen, "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. 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."

Cyrus doesn't rule out getting back together with the Jonas brother — though a source tells People magazine he's now dating fellow Disney Channel star Selena Gomez, 16.

"Maybe he'll be my best friend for the rest of my life or maybe I'll end up marrying Nick Jonas!" Cyrus says.

But for now, she's on her own.

"Since [the breakup], I've realized that I've met so many great guys, but I like being the girl nobody can have," she says. "No one can touch me, no one's mine. I'm myself. I think it's sexy to do your own thing."
