The 46-year-old actor, who announced his separation from wife Jennifer Aniston on Feb. 15, was spotted for the first time without his wedding ring on Thursday in New York City.
Theroux was casually dressed in an olive bomber jacket, white T-shirt and blue jeans, which he paired with black suede boots and aviators. It was the one accessory he wasn't wearing, however, that's the most noticeable: His left hand was clearly without his wedding band.
Coincidently, The Leftovers star wore a nearly identical outfit when he was snapped for the first time since the split was announced. The only differences were that he was also layered up in black hoodie, beanie and gloves that covered his hands.
The new pic of Theroux comes just two days after Aniston was spotted leaving her former Friends co-star and BFF Courteney Cox's Beverly Hills condo sans her wedding ring.
Since his and Aniston's breakup, Theroux has been laying low. He did, however, break his post-split silence on Sunday for a good cause. The star took to Instagram to share a photo of himself cuddling two adorable puppies during a visit with to Austin Pets Alive, a nonprofit organization in Texas.
