Miley Cyrus and fiance Liam Hemsworth had to "refall" in love with each other following their 2013 split.

The 24-year-old singer first started dating Australian actor Liam after they starred together in 2010 movie The Last Song. They got engaged in June 2012, but called off the engagement in late 2013. They rekindled their relationship in early 2016, and appear to be going from strength to strength.

Miley is gearing up to release new music, and has opened up about her on-off romance with Liam in one song titled Malibu.

Asked why she decided to write about Liam, Miley told Billboard magazine: "Why not put the power back in my relationship and say, 'This is how I feel'?"

Referring to their 2013 break-up, Miley added: "I needed to change so much. And changing with someone else not changing like that is too hard. Suddenly you’re like, 'I don’t recognize you anymore.' We had to refall for each other."

Miley has hit headlines in recent years for her often lewd onstage behavior and comments surrounding her sexuality. However, she added that when it comes to what she finds attractive in the opposite sex, it's not a "dude".

"I always get in trouble for ­generalising straight men, ’cause straight men can be my worst nightmare ­sometimes. And I’m with a straight dude. But he’s always like, 'Well, don’t call me that!' I ask him sometimes, 'Do you like being a boy?' And he’s like, 'I don’t really think about it.' And that’s crazy to me, because I think about being a girl all the time. I’m always like, 'It’s weird that I’m a girl, because I just don’t feel like a girl, and I don’t feel like a boy. I just feel like nothing.' So when someone’s too ­masculine, that really grosses me out."
