Kristen Stewart Looks Wiped As She Leaves Los Angeles [PHOTOS]

Someone looks like she could use some rest. Maybe she’s a little tired from her weekend of partying with boyfriend Robert Pattinson.

UsMagazine.com reports that Kristen Stewart and Robert attended a pre-Oscar bash at the Chateau Marmont in Hollywood Friday night (February 25). The costars “were dancing the whole time. They definitely kissed a few times.”

The highlight for Pattinson and Stewart? “They went nuts for Empire State of Mind!” the witness told Us.

So I guess Kristen, with her hand still in a splint, being at LAX today nixes those rumors that she and Rob would be attending the Academy Awards together tonight.
