Miley Cyrus' twerking knows no bounds.
The pop singer's MTV Unplugged special aired on Wednesday, Jan. 29, which once again proved that she can't be tamed. The set featured incessant tongue wagging, crotch grabbing and f-bomb dropping.
"I tried to bring Nashville here for the night," Cyrus told the California crowd. She often joked with the audience, telling them, "MTV's paying me today in ones so we can all go to the strip club after this."
During a country rendition of "4x4"—in which Cyrus sang that she's "driving so fast" she might "piss" on herself—the wigged wonder twerked on a giant horse. The former Hannah Montana star also reenlisted dancers Amazon Ashley and Little Britney to perform in her racy (and random) stage show.
Cyrus belted out a number of songs from Bangerz, including "Adore You," "Drive" and "Wrecking Ball."
Madonna joined the daring diva on stage for a mash-up of "Don't Tell Me" and "We Can't Stop." After the Material Girl joked that they could take it a step further, Cyrus playfully frisked her duet partner.
"That was pretty f--king cool, you guys," Cyrus told the crowd. "It sounds super lame, but as a pop star it's pretty cool performing with Madonna. Today was one of those days that was pretty easy to get out of bed. I get to perform with Madonna in bedazzled cowboy boots. I can't really complain about anything. Well, I can't perform when I'm stoned. That's one thing to complain about, I guess."
Cyrus later tweeted about the collaboration, writing, "I SPANKED @Madonna (hard) (& she liked it)."
