Long locks vs. short cuts

<b>Rihanna: Better Long</b> The singer changes her hairstyle just about as often as she changes her clothes. From short to long to blonde to black, RiRi loves to switch it up. On Wednesday, she displayed a shorter pixie cut with short bangs. She certainly has the gorgeous face to pull it off, but the jury is still out on this cut. We had just found ourselves getting used to her longer look. Check out these other stars and decide whether they look better long or short. <a target="_blank" href="http://www.x17online.com/celebrities/rihanna/rihanna_rocks_sexy_short_hair_mtv_awards_rehearsal_090612.php">Click here for more Rihanna photos from X17 Online.</a>   (X17 Online)

<b>Anne Hathaway: Better Long</b> The engaged actress was asked to cut her hair and lose weight for her current role in "Les Miserables." We prefer it a little longer, but she has beautiful features, so either look works for the petite actress. But, alas, not all stars are that lucky.  For more pics of Anne, go to <a target="_blank" href="http://www.x17online.com">x17online.com.</a>

<b>Jennifer Aniston: Better Long</b> As Rachel Green on "Friends" Jennifer Anistion set the standards for trendy hair for years.  Whether long or short, she looks great in whichever style moves her. But we can't help but love her with her signature long, California-girl locks.     (Reuters)

<b>Justin Beiber: Better Short</b> Justin became famous for his long shaggy 'do, but now that he's been on the scene for awhile, we prefer the shorter, more mature look... Minus the crazy eyes, of course.     (Reuters)

<b>Matt Damon: Better Short</b> For the "Bourne" trilogy Matt often kept his hair short and tidy, but some roles call for a longer more mature look. We like it spiky.  (Reuters)

<b>Gwyneth Paltrow: Better Long</b> Gwyneth's sleek golden locks look best long.    (Reuters)

<b>Emma Watson: Better Long</b> The "Harry Potter" cutie looks much older in her cropped 'do. It looks more playful and age appropriate when it's long.   (Reuters)

<b>Jessica Alba: Better Short</b> The gorgeous actress has such a tiny frame and features that she gets drowned out in long hair. The short sleek look is perfect on her.  

<b>Michelle Williams: Better Short</b> The "Blue Valentine" star has one of those faces that is better served with less hair getting in the way. 

<b>Ashlee Simpson: Better Long</b> Is there no in between for this petite songstress? Ashlee either goes for dramatic dark lengths or a short bleached 'do. A softer color with the longer locks would be best.   (www.x17online.com)
