Miley Cyrus Talks Ending Relationship With Liam Hemsworth, Fears Being Alone

In an interview with Barbara Walters, Miley Cyrus opened up about her past relationship with "Hunger Games" hunk Liam Hemsworth, saying she believes they moved too fast in getting engaged and that she grapples with the fear of being alone.

"I was so scared of ever being alone, and I think, conquering that fear, this year, was actually bigger than any other transition that I had, this entire year," Cyrus told Walters in the interview for the upcoming ABC News special, " Barbara Walters Presents: The 10 Most Fascinating People of 2013."

"I don't ever want to have to need someone again, where you feel like, without them, you can't be yourself."

Cyrus, 21, and Hemsworth, 23, were together for four years and announced their engagement in 2012, but the couple confirmed in September that they had called it quits. While she loved Hemsworth, Cyrus said, she believes she can now "actually be happy" on her own.

"I don't think I realized what 19 truly is, and I got engaged at 19, and I definitely wouldn't change being engaged," he said. "It was so fun wearing a fat rock for a few years," Cyrus said, "But now, I just feel like I can actually be happy. I wait for those moments of silence, when I'm just at my house, by myself."

Several tracks on the pop singer's latest album, "Bangerz," refer to love. In the song "Drive," Cyrus crones the lyrics, "I was crazy, thinking you were mine. It was all just a lie," but denied there was anything false about her and Hemsworth's relationship.

"I don't think there was any, any lies," she said.

When asked whether she ever wanted to be married and spend the rest of her life with someone, Cyrus said, "I think I'll want that in the times that it needs to be."
