The 21-year-old singer seemingly took several jabs at her ex-fiancé while introducing her hit song "Wrecking Ball" to concertgoers.
"Every time you get in your car, you're going to hear my [expletive] song on the [expletive] radio you piece of [expletive]," Cyrus says in her rant. "That's right. And then I'm gonna take all my clothes off, I'm gonna sit on a big, giant [expletive] -- sometimes two -- I'm gonna swing around."
"So I'm gonna tell those mother [expletive] that broke my heart, particularly one, to suck my fat [expletive] -- and to enjoy hearing this song for the rest of your life," she added later. "This song is called 'Wrecking Ball.'"
Cyrus later explained on Twitter that the comments "had nothing to do with Liam" and that she was "just trying rile up the boys."
"I don't usually respond to tabloidy stuff but this isn't something I want being spread around. It sounded hateful but not what I meant," she wrote.
The singer went on to say that she never wants hateful things to be said about the people she cares about.
"I was just tooooo turnttttt up," she tweeted.
