Aniston is in Atlanta to start filming director Garry Marshall's Mother's Day, which also stars fellow A-listers Julia Roberts and Kate Hudson. The 2016 comedy tells the intersecting stories of different moms colliding on Mother's Day, presumably in the style of Marshall's previous ensemble films, Valentine's Day and New Year's Eve.
And it must be a sizable new role -- a source tells ET the former Friends star brought along 12 suitcases and five garment bags with her, as well as multiple cases of Smartwater.
The newlyweds are currently spending some time apart for work, as 44-year-old Theroux returned to the set of his HBO hit, The Leftovers, in Austin, Texas, last week. Last Monday, he was spotted jetting out of LAX sporting his own noticeable new piece of hardware.
"It's nice to be able to look down and see a new piece of jewelry on my finger," Theroux recently told People about his wedding ring. "I'm very happy."
Jewelry designer Jennifer Meyer, who's married to Tobey Maguire, recently called designing her friends' wedding rings "an honor."
"Congratulations to my beautiful friend, Jennifer Aniston on becoming Mrs. Theroux ? Designing Jen & Justin's wedding rings was such an honor xo," she Instagrammed.
