MILEY CYRUS

Then: In January 2006, 13-year-old Cyrus was the squeaky-clean star of the Disney Channel's Hannah Montana. The show proved a launching pad for the actress, who later scored music and movie deals.
Now: Seven years later, on the verge of turning 21, Cyrus has shed her good-girl image by regularly stepping out in revealing clothing, chopping her long locks into an edgy pixie and releasing music that alludes to her party-girl ways. She's also got a new leading man in her life: fiancé Liam Hemsworth.
