Miley teamed up with Madonna for MTV’s “Unplugged,†a show that’s proved anything can happen onstage. Bringing some country flair to her routine, Miley entertained the audience with her usual antics -- tongue wagging, crotch grabbing and twerking. Still, it was impossible to ignore Miley’s powerhouse voice, which lent itself to tracks off her chart-topping album “Bangerz.†Near the end of the show, Madonna made a surprise appearance and the pair did their thing to Madge’s high-energy hit “Don’t Tell Me,†which morphed into Miley’s “We Can’t Stop.†It isn’t called “Unplugged†for nothing.
