Much maligned Twilight starlet Kristen Stewart looked lovely in Valentino at the New York premiere of her new indie, Welcome to the Rileys. Stewart’s radiance is likely owed to looking like less of a sourpuss than usual, whether that be from her fresh-scrubbed skin, minimal make-up and matte lips or, you know, getting to wear a gorgeous Valentino minidress.  Either way, she looks super fit and that smile seems only slightly begrudging.
