Miley Cyrus stole the show once again as she teamed-up with legendary Pop singer Madonna in a special episode of MTV Unplugged that airs Wednesday 9.p.m, twerking with her tongue out and dropping F-bombs all night long in Hollywood.

Cyrus taped the acoustic concert Tuesday on a Hollywood soundstage, performing stripped-down versions of her songs from her album, "Bangerz," and closing with a booty-slapping duet with Madonna.

"So, it sounds super lame, but as a pop star it's pretty cool performing with Madonna," the 21-year-old pop star said after singing a mash-up of Madonna's 2000 track "Don't Tell Me" and her hit "We Can't Stop." She playfully spanks the 55-year-old Queen of Pop during the duet.

It wass a hoedown, as they were backed by a seven-piece band on a stage decorated with hay bales. Miley Cyrus gave her acoustic songs a country touch, adding a twang to "4x4" and "Bangerz."

"I'm from Nashville," she said. "And since I couldn't make all of you guys go back home with me, I tried to bring Nashville here for the night."

She also includes elements from her more recent shows: a little person, a giant woman and two men in a horse costume. Miley works in a fair amount of curse words, tongue extensions and sultry moves as she performs songs including "Wrecking Ball," ''Adore You" and "Drive."

"I feel like I'm at karaoke, but it's only my turn," she said, "which is what I really like."

Both pop singers are known for their provocative and controversial performance that stunned the crowd and headline of every medium you can think of. We can never forget Miley's twerking performance with Robert Thicke at last years VMAs or Madonna's kiss to Britney Spears 10 years ago.
