Here are photos of Robert Pattinson and Kristen Stewart not being Edward and Bella but just being themselves at the Twilight Saga: Eclipse Premiere After Party! Kristen must have been tired of wearing her ridiculous one shoulder boulder holder gown because.

She changed into jeans and a tank-top. (NO Surprise, that's her usual get up)... Robert Pattinson was apparently to lazy to change out of his light gray dress shirt, skinny black tie and burgundy suite... nice... straight pimping! I'm not a big fan of Pattinson's outfit but I do like.
That Stewart changed... maybe she realized that it was the Twilight Saga: Eclipse premiere and that she looked lame... maybe... maybe not. Whatever. The premiere went off with only on hitch... Stewart's forehead was written on by a fan's sharpie so she had to go back to makeup. Besides that, every thing else seemed to go well.
