The 'Climb' singer told E! Online at the MTV Video Music Awards on Thursday (September 6) that her top priority right now is finishing her fourth album.
"I've got so much going with this record, this record's going to, like, kill me," she joked. "I'm really excited to get obviously married, but I kind of already feel married. I know we're forever and I don't really need a paper right now."
Cyrus continued: "[This record is] all really different. We've been working really hard on the record.
"I'm really proud of the album. It's my favourite thing I've done, probably ever."
Cyrus announced her engagement to Hemsworth in June, following his proposal on May 31.
"I'm so happy to be engaged and look forward to a life of happiness with Liam," she said at the time.
The couple then swiftly denied that they planned a weekend getaway wedding less than a month after confirming their engagement.
