Jennifer Aniston and her fiance Justin Theroux looked like the perfect pair last night in their matching black and white ensembles.

The couple attended the 26th American Cinematheque Award Gala honoring Jennifer's friend and "Along Came Polly" costar Ben Stiller.

Jen donned a simple but sexy Valentino dress, which she paired with a studded clutch. Of course all eyes were on her accessories -- including her giant emerald-cut diamond ring, which Jen reportedly showed off on the way to her seat -- and a new pair of spectacles.

Others honoring the comedian included Will Ferrell, Eugene Levy and Tom Cruise (via a video speech).
