Twilight co-stars and notoriously private couple Robert Pattinson and Kristen Stewart made quite a splash at a pre-Oscars party at the Chateau Marmont, according to Us Weekly.

The shy couple was “dancing the whole time,” a source says. "They definitely kissed a few times." Other guests at the bash included Miley Cyrus, Scarlett Johansson, Halle Berry and eventual Oscar-winner Natalie Portman.
