Perhaps you caught my slideshow of what's hot right now in hair color, in which celebrity colorist Johnny Ramirez described how he recently lightened Carey Mulligan's cropped pixie from a medium-toned red to a dark blond hue. On Friday, he paired up with Carey once again to create this much lighter shade, which we first got a glimpse of as she snuggled with boyfriend Shia LaBeouf on Valentine's Day, although she officially debuted her new look on the red carpet at a luncheon for the upcoming Academy Awards earlier today. "She just wants to have fun and be blonde," Ramirez told me of the actress's decision to lighten up. What do you think of the new look? Are you enlightened by this Mia Farrow-like style?
