Jennifer Aniston heated up the film set of "We're The Millers" in North Carolina yesterday when she flashed her flesh-colored bra for an extended period of time, to the delight of paparazzi, while shooting scenes for the upcoming movie.

The former "Friends" star, 43, kept her blouse unbuttoned for scenes on-camera and continued to leave it open during rehearsals.

As an added bonus to onlookers, Aniston's unidentified body double filmed her scenes wearing just a white lace bra and panty set.

The newly-engaged Hollywood star was filming with co-star Jason Sudeikis in Wilmington, N.C. In "We're The Millers," Aniston plays a prostitute who is hired by a drug dealer to play his wife in a fake family. The comedy also stars Emma Roberts and Ed Helm, and will arrive in theaters next year.

Roberts tweeted her excitement about working with Aniston:

"SO happy to be a part of We're The Millers!! Dream come true to work with Jennifer Aniston!"

Aniston got engaged on Friday, Aug.10, when her now fiance, Justin Theroux, proposed to her on his 41st birthday.

"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," his publicist told PEOPLE exclusively.

Insiders dished that the proposal took place at the Blue Hill restaurant in Manhattan's Greenwich Village.

The 41-year-old has been dating Aniston for over a year and they co-starred in the film "Wanderlust."

When paparazzi spotted the former "Horrible Bosses" star last week in North Carolina, Aniston turned the ring around to hide the stone inside her fist, revealing only a plain gold band to the photographers.

"It's a huge emerald-cut diamond," a source told Life & Style Weekly. "It's a rectangle with tapered diamond baguettes on the sides. It's beautiful."

Howver, on Aug. 20, E! News ran an exclusive photo of the ring Aniston keeps hiding.

This will be the second time Aniston will walk down the aisle: she was married for five years to "Moneyball" star Brad Pitt. Their marriage ended in divorce not long after he met Angelina Jolie, his co-star on "Mr. & Mrs. Smith."
