Miley Cyrus Twitter: Singer Shows Off Her Punk Rock Style On Social Media (PHOTOS)

Twitter/Miley Cyrus

Miley Cyrus is determined to show us she's all grown up from her former Disney star self.

The 20-year-old singer/actress took to Twitter over the weekend to display her increasingly punk rock style, tweeting photos of her and a gaggle of friends acting silly for the camera in skimpy, rocker-inspired outfits.

Cyrus flaunted her toned tummy in a crop top, baggy black shorts, stiletto sandals and a studded leather biker jacket, sticking her tongue out and throwing up peace signs for a posed photo and tweeting, "Girl in boys clothing. ♦♦♦"

Visibly absent from the photos was her engagement ring, given to her by reportedly on-again-off-again fiancé Liam Hemsworth.

The next day after her Instagram photoshoot, Miley was spotted puffing on a suspicious-looking cigarette on the balcony of her Miami Hotel room -- and again, with no engagement ring in sight.

Cyrus has undergone some dramatic style transformations over the years, donning increasingly edgier looks: from trading in her long dark locks for a bleach blond pixie cut, to her love of sideboob and tattoos, to her questionable, bondage-inspired outfits.

Check out the photos below and tell us what you think of Miley's punk rock look.
