I’ve told you this week about my theory (and I am sure it could be scientifically proven) according to which when a woman changes her man she also changes her hair. I would bet anything on this! I gave you Rihanna’s example, which wasn’t a very happy one, but a change is still a change. Now I’m giving you Kate Hudson’s case. The BLOND actress appeared curly brown hair on the set of her new movie, 'The Killer Inside Me', in Oklahoma City.

So, if we don’t know for a fact that she split from Owen Willson, we could tell it from the color of her hair. Note that this week I also told you about the rumor saying Kate is dating Yankees player Alex Rodriguez. So here is the proof!

PS: Kate is not the only one changing her hair color: Fergie also went to the dark hair while Kim Kardashian changed dark for blond wig.
