"The Hills" cast members may not have changed up their locks (besides a trim or a highlight here and there) during their televised Tinseltown tenure -- but recently, the good-looking gang has made a complete 180 with regards to experimenting with new styles. From mom-to-be Audrina Patridge opting for a (temporary) purple hue and mother-of-three Kristin Cavallari going for the major chop, these MTV gals are hitting the scissors and foils at the salon with reckless abandon. But perhaps the biggest transformation of all ensued over the weekend: Lauren Conrad is no longer a blond and is now rocking a fiery red shade.

In honor of LC's fresh copper strands -- let's remember the lifestyle maven has had a golden mane since that very first walk in the sand during her inaugural moments on "Laguna Beach" -- we decided to have a little fun with Photoshop and see what would it would look like if several of the SoCal MTV alums swapped hair. Take a look at our amusing makeovers below (grab your helmets like Lauren eloquently advised awhile back), and dish on your faves in the comments!

Audrina Patridge and Kristin Cavallari

It's ON: Drina looks cutesy with bangs, and being a (light) brunette certainly suits K-Cav.

Brody Jenner and Whitney Port

These two -- who recently hung out at the fashion designer's bachelorette bash in Sin City -- should probably stick to their current colors and lengths.

Lauren Conrad and Spencer Pratt

Yes, we know what we did. One word to describe this flip? Sucky. Like the aforementioned pair, their present looks work best.
