Once in a Blue Swoon: Hallelujah! Kristen Stewart has peeled off her well-worn pair of crankypants and slipped on a spectacular midnight blue Monique Lhuillier gown with a graceful sweetheart neckline and flared skirt. It's a sartorial love connection for the perma-squirmy "Twilight" starlet, who we think might still be sporting a restrictive and prickly pair of undies judging by her unsuccessful attempts to strike a happy-go-lucky pose. To her credit, Kristen nearly manages to crack a smile. Keep trying, K.Stew, because if there was ever an occasion to show some teeth, this is it. The minimal accessories (love the diamond bracelet), the on-the-cusp-of-maturity dress and tresses that have felt the touch of a comb this month come together better than an Edward-Bella-Jacob love triangle. Congratulations, Kristen, you've officially arrived.
