Call them the squeaky wheel, but it's no secret that celebrities often sport hairdo's that are wild, funky and sometimes just downright messy. As crazy as some of the styles are, we have to believe it's all in the name of attention -- not fashion. At least we'd like to think so.

Take a look at some of the stars who are making messes with their tresses, and then ask yourself if you would dare to wear that hair.

Ever since her days on "Friends", Jennifer Aniston's long, wavy, honey-blond locks have sent many a woman into salons clutching one of her photos. But when she appeared on "The Late Show With David Letterman" recently, the Hollywood trend setter was sporting such a tousled head, we had to wonder if the actress had been caught in a wind storm on the way in.

Victoria Beckham started a huge hair trend with her "pob" (posh bob) cut. It was a flattering combination of tousled and tame, but recently it's been less of the latter. When she attended the recent 18th Annual Elton John AIDS Foundation Academy Award Party in West Hollywood, Miss Posh Spice herself attempted an updo that was really more of a falling-down 'do.

Dakota Fanning has seemingly turned from girl to woman overnight on the big screen, and her hair is making an equally big leap with the ultra messy, rocker style she is sporting to promote her new movie, "The Runaways". Personally, we love seeing a little edginess and messiness, but this look is really more reminiscent of a 1960s bouffant gone terribly bad.

Tell us what you think. Are these celebs taking the natural, carefree look too far?
