Miley Cyrus sports a daring new hairdo.

Miley! You've shrugged off your girl-next-door innocence overnight.

The Southern songstress, who is engaged to Aussie actor Liam Hemsworth, has gone for quite the image makeover, lopping off her long brunette locks and opting for a daring platinum-blonde pixie cut.

The style is a far cry from the star's more famous sweetly demure look and includes shaved undercut sides. Matched with a barbed-wire necklace and nose ring, the Nashville girl beams in a set of images posted on Twitter.

Cyrus says she feels "pretty" with the 'do.

The goddaughter to Tennessee poster-girl Dolly Parton has undergone something of an epiphany, according to comments attached to the tweeted photographs revealing the new look.

"Never felt more me in my whole life ❤" writes Cyrus in one caption, while another is equally effusive: "❤❤❤ feeling so happy in my skin".

The pictures have been re-tweeted over 20,000 times and yet another tweet by the 19-year-old defends the inevitable opinionated backlash: "if you don't have something nice to say don't say anything at all. my hair is attached to my head no one else's and it's going bye bye :)"

Miley as we used to know her.

The Last Song actress and current Marie Claire US cover girl became engaged to Hemsworth, 22, in May. The young couple have defended their decision to tie the knot at a young age, Cyrus opening up to the magazine: "Life is too short not to be with the person you want to be with.

"I don’t really care about the wedding or the piece of paper as much as I do the promise we’ve made to each other. And we want to have a long engagement."

Her fans, predictably, have much to weigh in on that topic, too.
