Miley Cyrus is a woman on a mission. Now she's reached the grand old age of 19, the Hannah Montana star looks like she wants to shake off her squeaky clean image for good with something a little... dirtier.

The former Disney star was spotted pounding the streets of New York yesterday looking like she'd just left a grungy rock club.

Dressed in denim hotpants and platform Dr Marten boots, Miley finished off her new look with some chunky gold chains and a camouflage jacket wrapped around her waist.
