Twerk it for a Cyrus special

Miley Cyrus mashes it up with Madonna, twerks with her tongue out and drops a bunch of F-bombs on her upcoming MTV special, and she’s in fine voice while doing it.

While her whittled stomach and occasional crotch-grabs compete for attention, Cyrus really can sing, and it shows on her episode of MTV Unplugged.

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