Robert Pattinson and Kristen Stewart threw their hands in the air like they didn't care all night long at a Friday/Saturday pre-Oscar bash at the Chateau Marmont in Hollywood.
The costars and real-life loves "were dancing the whole time," a fellow reveler tells UsMagazine.com. "They definitely kissed a few times." (Stewart wore a black dress for the bash.)
Pattinson, 24, and Stewart, 20, were far from the only celebs getting their dance on to DJ Jesse Marco's mix of 80s, classic hip hop and pop:Hayden Panettiere and Miley Cyrus (dancing to her own "Party in the USA"!) were spotted on the dance floor, whcih was also flooded with stunning models. Stars like Scarlett Johansson, Halle Berry, Ryan Gosling and Natalie Portman also stopped by.
The highlight for Pattinson and Stewart? When a certain Jay-Z/Alicia Keys Big Apple classic came on around 1 a.m. "They went nuts for Empire State of Mind!" the witness tells Us.
