Since firing stylist/friend/etc. Rachel Zoeyesterday, Nicole Richie's seemed a little touchier than usual - yesterday, while we were trying to get set up to snap a few shots of Nicole climbing out of her SUV, she started demanding that we step even further back than we'd already moved! What on earth could she have had to be nervous about? After all, general consensus around the office is that she's a hell of a lot better at making herself look good than Rachel ever was!
