Heroes star Hayden Panettiere showed up at the Green Inaugural Ball last night in Washington D.C. looking HOT! She worked a strapless black, deep v-neck, tight mini-dress with blue and black crystal embellishment artfully worked in. Her hair was pulled back in a soft, effortless updo and her make up was classy and beautiful.

It still blows my mind that this chick is the little girl from Remember the Titans. Home girl grew up to be a super hottie!
