We've previously reported how Miley Cyrus has transformed into quite the rock chick since cropping her hair and dyeing it blonde, taking her style cues from Brit grunge icon Agyness Deyn. But she's not the only former squeaky clean pop star who has used a bottle of bleach and a wardrobe of leather and ripped denim to update her image.
When Ashlee Simpson first stepped on the scene with debut single ‘Pieces Of Me’ in 2004 she was the wide-eyed little sister of MTV reality queen Jessica. Although clearly desperate to be dubbed 'alternative' her darkened locks and 'Punk' vest top reeked of teenage rebellion. Cut to eight years later and the now 28-year-old mother of one boasts a beautiful blonde barnet and enviably sophisticated rock 'n' roll wardrobe.
As Ashlee and Miley shake off their formative style it's only served to help their careers rather than upsetting fans. In Miley's latest music video 'Decisions' - a collaboration with Israeli producer Borgore - the singer once and for all rejects the fresh faced, curly haired Hannah Montana character she played for so many years and embraces her inner hedonistic wild child. Not only does she get stuck into a cake fight, she full on snogs fiancé Liam Hemsworth (disguised as a unicorn) and sticks out her unusually long tongue, which we're taking to mean 'I'm a grown up, deal with it punks!' Similarly Ashlee's new promo for 'Bat for the Heart', her first single since 2008, is full of raunchy behaviour. Shot in black and white, the video sees the singer writhing around in a t-shirt, performing impressive ballet moves in her knickers and dropping the F-Word.
But which of the pair is the more authentic rocker? Sure Ashlee's got a Pete Wentz as an ex and no Disney in her past, but Miley is really letting loose with her image - shaving her head and not leaving the house without a pair of Dr Martens. Take a look through our gallery above and decide who is the ultimate child-star-turned-rock chick.
