MET Matchup: Kristen Stewart vs. Jessica Biel

Neither Kristen Stewart nor Jessica Biel are known for smiling. They never seem excited to be photographed.

This attitude persisted for both beauties last night, as they joined a slew of celebrities at the Metropolitan Museum of Art's Costume Institute Gala, which was held in honor of a future exhibit called "American Women: Fashioning a National Identity."

Stewart's identity, whether she likes it or not, is often based on her relationship with Robert Pattinson, although that Twilight Saga hunk didn't accompany his girlfriend to the event.

Biel did walk the red carpet with Justin Timberlake, but we've shoved that singer aside in the photo below in order to pit Jessica against Kristen. Who looked better?
