That was fast!

Kim Kardashian appears to have dyed her hair back to brunette after being a platinum blonde for less than a month! We caught her driving in L.A. yesterday, and it certainly looked like she was donning darker locks, although we guess it could have been a wig.

The reality star posted an Instagram of herself with brown tresses at a photoshoot with Ellen von Unwerth, so it's almost like she wants her fans to get caught up in a guessing game. She better be careful with how much she messes with her 'do, because too much processing could make her hair fall out, and then she will look identical to her nemesis Amber Rose!
