Miley Grinds On Madonna, Madonna Grinds Back

Here is part of an MTV article on Madonna's appearance and Miley's reaction to their duet on MTV Unplugged:

....specifically with Madonna, who, as you've likely heard by now, had been quietly hiding in plain sight, rising from the audience in a bedazzled cowgirl uniform to join Miley on a mash-up of 'Don't Tell Me' and 'We Can't Stop.' While trading off and exchanging lyrics of both hits, Miley grinded on Madonna, Madonna grinded on Miley, they both box-stomped and turned line dancing into dirty dancing, and yet another legendary pop music moment was made.

'That was pretty f---ing cool, you guys. It 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,' Miley effused as Madonna two-stepped off the stage. 'Well, I can't perform when I'm stoned. That's one thing to complain I guess,' Miley teased before impersonating 'Saturday Night Live''s Vanessa Bayer's cheeky impression of her, capping off the unforgettable duet by confirming it was 'pretty cool.'
