The public appearance was her first since it was revealed thatCyrusand her husband of less than a year had called it quits.

Released days after the break-up became public, the new song gave Cyrus the chance to open up about the breakdown of their union.

Cyrus goes on to make a drug and alcohol reference, singing, “I want my house in the hills / don’t want the whisky and pills / I don’t give up easily but I don’t think I’m down.”

Days after the song’s release, the 29-year-old Australian actor filed for divorce.

According toThe Blast, Hemsworth — who has hiredfamed Hollywood divorce attorney Laura Wasser— cited “irreconcilable differences.” The pair signed a prenuptial agreement ahead of their marriage, so a smooth divorce is expected, PEOPLE confirms.

Reps for Hemsworth and Cyrus did not immediately respond to PEOPLE’s request for comment.

Cyrus added: “At this point I had to make a healthy decision for myself to leave a previous life behind. I am the healthiest and happiest I have been in a long time. You can say I am a twerking, pot smoking, foul mouthed hillbilly but I am not a liar. I am proud to say, I am simply in a different place from where i was when I was younger.”
