Jennifer Aniston was spotted today on the Carolina set of her new film We're the Millers, in which she plays an apparently dowdy prostitute.

The 43-year-old is following up her well-received performance as a sex mad dentist in Horrible Bosses with another star of that film, the perennially amusing Jason Sudeikis.

And there's a reason for her
character's humdrum attire as the film follows Sudeikis' pot dealer as
he creates a fake family in order to smuggle 1,000 pounds of pot across
America.

Aniston plays a prostitute hired to
play Sudeikis' wife and obviously the films backers are hoping that
after the Horrible Bosses success, hilarity will ensue.

Today Aniston was filming perhaps the start of that journey as she wheeled a suitcase around with Roberts sometimes in view.

She was dressed in khaki trousers and a light blue sleeveless blouse with cut-out pattern.

The former Friends star's hair was tied back and a tiny practical purse was slung across her dainty shoulders.

White pumps were on her feet, all the better to run with… it can presumed.

It was a far cry from her usual level of glamour, it has to be said.

Aniston has brushed off reports that she is headed down the aisle.

The actress, who is said to have rejected Justin Theroux's proposal during their recent European holiday, says marriage and kids may not be in the cards for her – because she considers the 'perfect life' a clich.

In the new issue of GQ Spain, the 43-year-old star says she's not bothered by the constant pressure from the press to settle down and start a family.

She recently enjoyed a romantic trip in Europe with Theroux, though the pair have been forced to separate due to work commitments.
