The 15-year-old teen revealed parts of her private life in the September edition of Seventeen magazine.
The star explains, "We became boyfriend and girlfriend the day we met. 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.’"
The two singers have never outright stated that they were dating, but merely said that they were only good friends.
"Nick and I loved each other," Cyrus is saying now. "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."
The couple broke up at the end of 2007.
The Hannah Montana star is now single and seems to be doing well. "Since [the breakup], I’ve realized that I’ve met so many great guys, but I like being the girl nobody can have," she said.
