From extreme plastic surgery to hairstyle overhauls, the most dramatic morphs of the year
1. January Jones
The Mad Men actress has said that when it comes to her red-carpet fashion choices, she tends to steer clear of anything the former Mrs. Don Draper might wear. This line of thinking apparently applies to her beauty choices, too: In a bold break from Betsy's classic '60s makeup, Jones flaunted futuristic high-fashion eye shadow at the Metropolitan Museum of Art's Costume Institute Gala in May.
The pop star might be "the only girl in the world" besides Lady Gaga who can seamlessly transition from one bold hairstyle to another in the blink of an eye. After switching from a blond pixie to a fiery-red one, Rihanna went even further, flaunting a hot, extension-fueled mass of curls at the American Music Awards in November.
3. Joaquin Phoenix
Following his announcement in 2008 that he was retiring from acting, the world watched as Phoenix plummeted into a seemingly downward spiral-from his deteriorating hygiene to bizarre rapping aspirations, the onetime leading man appeared to have hit rock bottom. Enter 2010: Shortly after shedding his beard and shades, news breaks that Phoenix was actually in character for a fake documentary about his life, I'm Still Here, directed by brother-in-law Casey Affleck.
4. Jennifer Hudson
Since starting the Weight Watchers program earlier this year, Hudson has taken her sexy, curvaceous bod down a few dress sizes. As a spokesmodel for the slim-down system, the Oscar winner says she feels "empowered" by what she's learned about portion control and healthy-yet-satisfying foods.
5. Ashlee Simpson-Wentz
A study released by the University of Michigan this past summer confirmed what we've all observed at one point or another: that over time couples begin to look eerily similar. This certainly seems to be the case with Ashlee Simpson-Wentz and her rocker hubby, Pete. For most of 2010, the pair had matching jet-black strands. After a brief ombré stint (shown here), however, Ashlee decided she preferred Pete's cut over his color-and got a shaggy platinum pixie.Ashlee Simpson
6. Heidi Montag
After going under the knife for a staggering 10 plastic surgeries in one day-including a second nose job and boob job-Montag revealed her new body in January 2010. Since then, she's publicly complained of postoperation woes ranging from inhibited facial movement, fear of her nose falling off, and immobile breasts in need of massaging. Hmm…maybe Montag will get 10 more corrective plastic surgeries in 2011.
7. Kelly Osbourne
After getting whipped into shape during her 2009 stint on Dancing With the Stars, Osbourne kept up her newfound fitness regimen-and her svelte figure in 2010 is proof! Besides better eating habits and Pilates, the reality-TV star says she continues dancing in order to maintain a healthy weight.
8. Kate Gosselin
"Everyone wants it!" Gosselin bragged to Entertainment Weekly in 2009 when asked about her reverse mullet do. "My hairstylist gets calls from all across the country." Thankfully, celebrity mane master Ted Gibson got his hands on Gosselin's strands in 2010 and smoothed out her spikes with extensions.
9. Emma Watson
Don't call her Hermione! Breaking free of her bewitching tresses and getting a pixie cut over the summer, Watson proved she's ready to graduate from Hogwarts.
10. Nicole "Snooki" Polizzi
Besides being addicted to pickles, the Jersey Shore star is also hooked on big hair-or at least she was. After causing a "pouf" sensation, Snooki retired the hairdo and emerged bouffant-less in 2010.
