Jennifer Aniston and her fiance Justin Theroux attended the 26th Annual American Cinematheque Awards honoring Ben Stiller in Beverly Hills on Thursday. It was the couple's first red carpet appearance together.

Jennifer looked amazing in a black and white strapless Valentino gown, and her beau wore a matching tuxedo.

Justin gave the actress an enormous 8-carat diamond ring when they got engaged in New York City in August. Last month Aniston got teary eyed and "verklempt" while taking about him to her her pal Chelsea Handler's talk show.

Aniston stars in the upcoming film "We're the Millers" about a pot dealer who creates a fake family to move a huge shipment of marijuana from Mexico into the United States.
