Jennifer Aniston may currently be busy planning her wedding to fiancé Justin Theroux, but the famous Hollywood actress must still pay her bills. Thus, the 43-year-old Aniston is reportedly back on the set as she arrived on location in Santa Domingo Pueblo, New Mexico to film scenes for her latest film "We're The Millers" which also stars Jason Sudeikis and Emma Roberts.

On the set, Jennifer Aniston was spotted wearing a thick-rimmed black spectacle, light blue top with a dark cardigan and khaki trousers as she worked with Jason Sudeikis when they filmed a scene in which Aniston's character drives a recreational vehicle across the United States of America and Mexico border.

"We're The Millers" is directed by Rawson Thurber and the film is a black comedy about a drug dealer who creates a fake family in order to smuggle drugs in to the United States. Filming is set to be finished by the end of this month with the location moved from North Carolina to Mexico.

According to reports, it was in North Carolina where Jennifer Aniston was spotted after Justin Theroux popped the big question. At that time, the actress even played coy with the photographers as she hid her engagement ring to prevent the world from seeing the stone, which reportedly is an 8-carat emerald-cut diamond.

Besides her very busy work schedule, Jennifer Aniston is also busy preparing for her big day though the engaged couple have not officially announced the exact date of their wedding.

Friends of the actress have also revealed that Jennifer Aniston is now ready to get pregnant even if that means she will have to show a baby bump during her wedding ceremony.

"It's no secret she wanted a baby so they're not wasting any time," the source shared. "She's not in denial. She knows it may be difficult," the source further added.

The wedding will be a second for Jennifer Aniston whose first marriage to Brad Pitt ended back in 2005. Since then, the actress has dated a string of men including Vince Vaughn, Bradley Cooper, John Mayer and Owen Wilson. All the relationships have all been short-lived until she met Justin Theroux.
