Fabulous and 43!

Playing a prostitute in We're the Millers, Jennifer Aniston has thus far stayed frumpy and covered up as she shoots the dark comedy with Jason Sudeikis and Emma Roberts in Wilmington, North Carolina. That all changed on Thursday, when the actress was snapped on set showing off her Yoga-taut figure in a super-skimpy look: Tiny, ripped Daisy Duke jean shorts and a clingy, skin-tight white tank top. Aniston (whose man Justin Theroux has stayed behind in NYC) wore her dirty blonde locks in a casual up-do, and appeared to be wearing minimal makeup and just gold earrings, pendant necklace and a simple bracelet.

In the film, Sudeikis plays a pot dealer attempting to smuggle a huge shipment of marijuana across the country -- hiring Aniston's prostitute as his fake wife.

Before Thursday's eye-catching ensemble, Aniston has been seen in much less revealing downright dowdy attire for the film.

"First day of filming on We're The Millers," Aniston's star-struck costar Emma Roberts, 21, tweeted last month. "So excited I woke up an hour early which I can assure you never happens." On July 17, Roberts tweeted that working with Aniston is a "dream come true."

Before getting down to work on the film last month, Aniston and beau Theroux, 40, enjoyed an extended European vacation capped off by a sun-filled, five-day trip to the island of Capri -- which included a June 19 jaunt on a rented luxury yacht, where Aniston showed her famous body in a skimpy two piece.
