Miley Cyrus says she hasn't been dwelling on.
The "Wrecking Ball" singer opened up about the couple's split during an appearance on "The Ellen DeGeneres Show."
"I think people spend more time actually thinking about it than I really do," the 20-year-old said. "I just believe when a chapter is done you have to close it and start that new one. That's kind of where I am right now. I felt like I have so much to be thankful for at this time that my energy hasn't really been focused on that."
Cyrus also told host Ellen Degeneres that her new album, "Bangerz," draws from her relationship with Hemsworth, whom she began dating in 2009 andto last year.
"The whole album is a story of that, and I think it says that with starting with 'Adore You' and ending with 'Someone Else,' I feel like you can really find like this arc of growth," she said, adding that she didn't realize how personal the album was until it was completed. "I think I knew more intuitively where my life was going then I actually thought I did at the time."
Cyrus also revealed she hasn't been in contact with "The Hunger Games" star since their split.
"I really haven't gotten to see anyone right now, because I've been so crazy busy, I'm just letting that chapter kind of close and just looking forward to that new one," Cyrus explained. "I want to be really clear and determined with everything I'm doing in my life right now, and I have been. I keep saying I'm the happiest I've ever been and that's not even a dig. That's just me, because I really am genuinely happy finally with myself, which I think sometimes it takes you separating yourself from someone else to really be happy with who you are."
"I've never been able to just be alone, and I'm obsessed with being alone and like hearing my thoughts," she added.
Cyrus' "Bangerz" was released on Tuesday. Watch her chat with DeGeneres below:
