Justin Theroux shows support for Britney Spears as he takes his beloved dog Kuma for a walk in New York City

Justin Theroux showcased his muscular arms as he took his dog for a walk in New York City on Saturday. 

The hunky actor, 52, who was recently seen on a rare public outing with girlfriend Nicole Brydon, kept it casual as he strolled through the city with his dog Kuma. 

The White House Plumbers star wore a sleeveless Britney Spears concert T-shirt and distresses skinny jeans and multi-toned sneakers for his outing.

The False Positive actor tried to keep his appearance low key, wearing a black billed hat and aviator sunglasses.

His dark beard was neatly trimmed and he carried a backpack.

The avowed dog lover tied Kuma’s leash around his waist, but opted to guide the pup who looked stylish in an animal print collar. 

The actor adopted the rescued dog in 2018, and often foster other pups until they can find their fur-ever homes. 

In March, Theroux made a surprise appearance on Saturday Night Live, helping funny guy Kyle Mooney get buff in a sketch. 

In an interview with Men’s Journal in July 2021, The Mosquito Coast star spoke about the importance, for him, of staying physically fit.

‘Fitness is extremely important, but like anyone I almost always dread it,’ the Emmy winner admitted.

‘That being said, when I go for even short stretches without some form of movement, I find my mood and general mental health suffers.’

‘It seems antithetical, but exhausting yourself in a workout almost always pays dividends later in the day by boosting mental and physical energy.’

In his twenties, the Mulholland Drive star said he stayed fit by walking around New York, or riding his bike. The native New Yorker can still be seen cycling around his home town.
