Hilary can't seem to make up her mind between a youthful golden blonde or a more mature chestnut hue. It seems she's gone back to her "Lizzie Maguire" look, but we're fine with that; she's got plenty of time to look "grown-up."
We're thrilled Christina has stopped channeling her former role as Wednesday Addams and has gone for lighter hair and softer makeup. Plus, the bangs perfectly balance out her heart-shaped face.
While Jessica gave old Hollywood glamour a spin with her long brown waves and scarlet lipstick, we must admit that we like her best in a sunny blonde hue with natural-looking makeup.
We're partial to Mischa's chocolate-hued before look; it warms up her complexion while the blonde washes her out a bit (plus the curls and red lip are gorgeous).
