The 20-year-old entertainer wore only a pair of boots as she sings about a failed romance atop a wrecking ball, which is reportedly about her relationship with fiance Liam Hemsworth, reported Ace Showbiz.
"Don't you ever say I just walked away. I will always want you. I can't live a lie, running for my life. I will always want you... I came in like a wrecking ball. I never hit so hard in love. All I wanted was to break your walls. All you ever did was wreck me. Yeah you wreck me," she sings.
