Michelle Obama

 The first lady has sported deliberately messy locks on numerous occasions—and more than one state dinner: She did it at the dinner honoring Mexican President Felipe Calderon last year, and at the White House Correspondents' dinner in April. Her hairstyle to greet German Chancellor Angela Merkel on Tuesday, however, may have been the messiest yet, and proved that one doesn't have to stick to stereotypical political helmet-hair.

Brigitte Bardot

And God Created Woman star Brigitte Bardot seems to be the inventor of the bed-head look—the pillow-lipped modern icon was the first to make the failure to brush one's hair look downright sexy.

Blake Lively

Fashion's "It Girl" Blake Lively has transitioned seamlessly from a blond to a ginger—but one thing has remained consistent throughout: hair that looks slept in. But Lively knows when to muss up her locks and when to put on the polish—and because she looks so damn good in clothes, the Gossip Girl star pulls it off.

January Jones

Bed head is a favorite style for January Jones—who debuted the 'do unintentionally during an infamous walk-of-shame last June after she spent the night at a special friend's house. Though the sleepovers may have ceased, the Mad Men star continued sporting the style on the red carpet—wearing loose curls with a Versace corset dress at the Emmy Awards last summer.

VERDICT: Fail

Kristen Stewart

After several surly comments, swapping heels for Converse sneakers, and favoring hoodies over dresses, Twilight star Kristen Stewart makes it obvious that she doesn't care about dressing up. So, of course, au natural hair is a K-Stew staple. But while it works on her boyfriend, we think Bella should tame her tresses.

Robert Pattinson

Robert Pattinson's bed head is appealing, perhaps, because it relies on filth. Its ability to stand up against the elements relies on a thick patina of dirt clearly achieved through days of skipping the shower. But somehow, he still looks good.

Kingston Rossdale

Gwen Stefani and Gavin Rossdale's 4-year-old son, Kingston, is one badass toddler: He wears camo, likes nail polish, walks the runway—and has platinum-blond hair. And because the pre-K celebrity baby is still developing motor skills, we'll forgive the lack of combing.

Ke$ha

Few define hot mess like this musical sensation. Though her hit with 3OH!3 mentions a man running fingers through her hair, we'd imagine he'd encounter some small animals dwelling within.

Kate Moss

The British supermodel has bed head no matter what she does—whether it's strutting the catwalk, clubbing late at night, or popping out for a stroll. But even when she briefly dyed her hair gray last year, it looked chic.

Russell Brand

The zany Mr. Perry's hair seems to rival a rat's nest—but he insists it's in good shape. As he once told Meredith Vieira, "I've had a series of good opportunities. I've behaved well, had a shave, and brushed my hair." Somehow, it doesn't seem to have worked.

Carine Roitfeld

The former editor of French Vogue epitomizes European cool: lace and leather, sky-high heels, and, of course, hair that looks like it has never seen a comb.

GRADE: Encore!

Julian Assange

As has his website, WikiLeaks founder Julian Assange has gone through many a hairdo over the years. But perhaps the most fitting for the hacktivist is, as The New Yorker wrote, his "mop of silver-white hair." As the profile explained, the long locks signify his dedication, since he had volunteer Birgitta Jonsdottir cut it as he worked. Nothing says sexy like a man with that much devotion.
