AMANDA SEYFRIED WOWS IN THREE OUTFITS

Working a new grown-up glamour on the red carpet at the Las Vegas premiere, Amanda also added a pair of dove grey Calvin Klein Collection suede courts showing off her endless legs while also complementing her look with her trademark golden locks worn loose over her shoulders and a serious slick of glossy red lippy.

We can't wait for more red carpet outings from this fashion-forward young actress.
