Who could it be?

CelebNewsWire says: "Tasty former stylist skewers" -- the closest Nicole Richie gets to food
Defamer says: Nicole Richie's MySpace blog a place for writing blind items about former friends
Dlisted says: Nicole Richie's blind item
Hollywood Rag says: Nicole Richie posts blind item
I Don't Like You In That Way says: Rachel Zoe is a good guess

Mollygood says: Raisin lettuce face cup vs. N-rich: fight

Who said it best:
A Socialite's Life isn't really taking sides, but...:

In the stylist's defense, I have to give her some credit for making Nicole look half-way human.... Does anyone else recall a lot of pink halter tops and denim shorts way back on The Simple Life season one?
