The actor was spotted at a cocktail party in Morocco with British actress Liz Hurley.
The event came to mark the ABB FIA Formula E Championship at the Amanjena Resort in Marrakesh.
Departed star Theroux, 47, seemed in great spirits as he was photographed in Morocco with his friends.
He showed off his fun side as he posed next to a collection of motor vehicles at the star-studded event.
The actor is known to like outdoor pursuits and also has a love of fast cars and motorbikes as well.
Justin Theroux and Aniston got a divorce in December 2017 after two years of marriage.
He described the split as pretty “painless” and that there was no “animosity” between the pair.
Aniston remained in Los Angeles and Theroux moved back to New York as the couple continues to lead separate lives.

Theroux sported a heavy beard and dressed in his trademark black as he posed beside several of the off road vehicles.
The actor was all smiles as he checked them out ahead of the race in Morocco.
Theroux recently spoke about his very public split from former 'Friends' beauty Aniston.
"The good news is that was probably the most — I'm choosing my words really carefully — it was kind of the most gentle separation, in that there was no animosity," he said.
He added: "Again, neither one of us is dead, neither one of us is looking to throw hatchets at each other," he jokingly added. "It's more like, it's amicable. It's boring, but, you know, we respected each other enough that it was as painless as it could be."
However, he did admit that it had been tough to adjust to their new lives. He added: "It was heartbreaking, only in the sense that the friendship would not be the same, as far as just the day to day."
