The Leftovers star, 47, has been getting used to the single life after separating from Aniston at the end of 2017.
The two officially announced the breakup in Feb. 2018 but had split in the holiday season of 2017.
Theroux took Kuma, his pit bull, for a walk on Dec. 26, the day after Christmas in the Soho area of New York. The actor/writer has settled there after his marriage split.
He bundled up in black but brightened up his outfit with a festive red stocking cap.
As Radar has reported, a source said Aniston was planning to spend the holidays with BFF actor pal Jason Bateman and his wife Amanda in Mexico.
After ending things with the famed Friends star, 49, The New York Times ran a story called "Justin Theroux is on the prowl," and noted, "Being married to 'America’s sweetheart' didn’t work out. So Mr. Theroux is back in New York, hanging with his buddies, partying at night and keeping it cool."
But after Christmas, Theroux looked to be without anyone to keep him warm—except for man's best friend!
