So are you ready for Hollywood's biggest night? Do you have your office pool all set up? You know, the one that predicts who is going to win Best Actress, Director, Film, etc. at this year's Oscars? Guessing who's going to take home the little, gold, bald guy is half the fun of the Academy Awards hoopla, right? The other half of the fun, for any hair, makeup, fashion-loving fiend, is seeing how your favorite celebrities look at the momentous occasion. See, there is a reason why the pre-show on the red carpet, detailing every inch of a celebrities' look, lasts almost as long as the show itself.

So in the spirit of Oscar predictions, we have decided, after careful consideration, to select some of the best celebrity hairstyles previously seen on the red carpet, and with the help of our good friend Photoshop, we popped them on the heads of this year's lovely nominees, presenters and guests. These "new" styles are what we think these celebs should wear as they parade down the carpet. So, should Sandra Bullock wear Meryl Streep's winning look from a previous Academy Awards ceremony? Or would she look better in a Penelope Cruz-inspired 'do? Will Maggie Gyllenhaal beat out Anna Kendrick with a classic updo that always works so well for Kate Winslet? And because Nicole Kidman and Kate Hudson aren't nominated for Oscars this year (though they will be there), should they opt for a low-key style so they don't upstage the great Helen Mirren? There really is just so much to consider.

While there is no money to be won on this pool, there sure is a good amount of fun to be had in predicting and suggesting who should wear what (previously-worn) celebrity hairstyles. Let the guessing games begin.
