Jennifer Aniston Wears Tight Strapless Dress, Flaunts Giant Engagement Ring at We're the Millers Premiere in New York

Actress walks the red carpet without fiancé Justin Theroux, but does pose for pics with costar Jason Sudeikis

Jennifer Aniston left the stripper wear on the set and went for old-Hollywood class on the red carpet tonight.

While we don't necessarily agree with the length of this strapless, deep-plum dress (and cut of the top is a bit of a bust as well), the rest of the actress looked pretty great Thursday at the premiere of We're the Millers in New York City.

Aniston, who at least spent a fair amount of the We're the Millers trailer in various states of undress, plays a stripper who's enlisted by her small-time pot-dealer neighbor to smuggle a load of marijuana from Mexico into the U.S.—and they pose as the parents of Emma Roberts and Will Poulter to make their border-crossing story more believable.

Raunchy hilarity ensues!

Justin Theroux, who's been in New York shooting the upcoming HBO series The Leftovers, was nowhere to be seen on the red carpet, but it wasn't immediately known whether he may have slipped into the premiere undetected or was planning to meet up with his fiancée later.

Aniston did, however, pose for pics with her fake-onscreen-husband Sudeikis, who showed up with Olivia Wilde on his arm. Wilde smiled for the cameras, then gave her fiancé a kiss and left him alone in the spotlight to do interviews, prompting boos from the paparazzi as she sauntered off.

And when Aniston was posing solo, the cameras couldn't help but pick up on that gigantic diamond engagement ring of hers.

Let's just say, Theroux was definitely there in jewelry spirit.
