Miley Cyrus
really is just a wild child! 

The singer showed off her sexy dance moves backstage at KIIS-FM's Jingle Balls. The video was posted by Miley's BFF Cheyne Thomas via Instagram on Friday in what looks like a hotel room. 

Check out Miley's new moves below (it involves butt slapping)!

Well, there's no denying that the 21-year-old is, more than confidant when it comes to strutting her stuff!

The "Wrecking Ball" singer still looks pretty great, dressed down sporting black baggy pants and a white T-shirt. It also looks like she's not wearing much makeup in the video either.
