The former Disney star showed off her new rocker side (and super-skinny stomach) at Sunday night's "VH1 Divas 2012" concert -- sporting a cropped leather jacket while performing Billy Idol's classic hit "Rebel Yell."
The performance was definitely one of the buzziest moments of the night, as it was her first televised gig since chopping off all her hair.
And she's definitely channeling her inner rock goddess now!
Check out the performance above. What do you think of the brand new Miley?
The show was packed full of performances from other stars too -- including Demi Lovato, Kelly Rowland, Jordin Sparks, newly-engaged Kelly Clarkson, Ciara, Keri Hilson and host Adam Lambert.
