Dakota Fanning smashed any remembrance of her child star-status when she showed up to the New Moon premiere in a sophisticated and sexy black lace strapless mini-dress.

Yep, I just used the word "sexy" in the same sentence at "Dakota Fanning."

Not only did she show off some impressive leg, but the girl worked the red carpet in blood-red platform heels, to boot!

Sorry Kristen, we love you for trying (and failing) with the princess gown, but this is how to make a splash at the premiere!
