Aniston, 46, looked chic in an all-black Roland Mouret ensemble as she attended the Los Angeles premiere of her upcoming film, "She's Funny That Way", reported E!online.
And while all eyes were on the A-lister's ring finger, it seems as though she was sporting her wedding band sans the engagement diamond bling.
"It feels quite natural," Aniston said.
Her husband wasn't able to attend the premiere, however, and the actress said that "he's shooting 'The Leftovers' in Austin."
The actress' red carpet appearance comes after Theroux was spotted landing at LAX airport shortly after his honeymoon in Bora Bora.
After a three-year engagement, the couple was also able to say "I Do" August 5 in an intimate ceremony at their Bel-Air, California, home.
Guests included Courtney Cox, Ellen DeGeneres, Rachel McAdams, Howard Stern and many other famous friends.
