The former Hannah Montana star stunned fans in June by announcing she is heading down the aisle with Australian actor Liam Hemsworth.
But Cyrus admits she has yet to begin organizing the ceremony as she is too busy preparing her upcoming release.
Speaking at the MTV Video Music Awards in Los Angeles on Thursday, she explains, "I'll have a single out this year.
This is the first time I get to tell people about it, so I'm really excited. It's all really different. We've been working really hard and the record, I'm really proud of the album. It's my favourite thing I've done, probably ever."
The 19-year-old star insists she is in no rush to marry and is happy to enjoy a long engagement.
She adds, "I've got so much going with this record. This record's going to, like, kill me. I'm really excited to get obviously married (sic), but I kind of already feel married. I know we're forever and I don't really need a (piece of) paper right now." (PAW/WNWE/ZN)
