Beyonce, Miley Cyrus, Anne Hathaway and All the Biggest Celebrity Makeovers of 2012 (PHOTOS)
Bold haircuts were responsible for changing some of Hollywood's most famous faces -- and setting major trends -- in 2012.
But hair wasn't the only thing transforming some of Tinsletown's brightest stars. Some of our favorite celebs went through some major weight ups and downs this year as well.
A few inches off the top of her head wasn't all Hathaway lost for her Les Mis role this year -- the Oscar hopeful turned to extreme dieting to lose 25 pounds to play the dying prostitute.
After giving birth to her first child, Jessica Simpson went with a more healthful approach to shed the baby weight, signing on as Weight Watchers' newest spokesperson to help her shed the rumored 70-plus pounds she gained during her pregnancy. The new mom recently revealed her jaw-dropping weight loss before announcing her second pregnancy earlier this month.
Some stars, however, weren't satisfied with just one transformation, shocking us with multiple makeovers in 2012.
Moneyball star Jonah Hill slimmed down in the later half of 2011, leaving fans shocked by this actor's almost-gaunt appearance. But by mid-2012, Hill had filled out to almost his original weight from years prior.
No stranger to shocking looks, Ke$ha shocked critics and fans alike when she showed off a glam new look at the American Music Awards. But it wasn't long before the edgy singer ditched her blonde waves and soft makeup for a goth-inspired hair and makeup.
