Justin Theroux, 54, and his pregnant wife Nicole Brydon Bloom, 31, frolic in NYC blizzard

Justin Theroux and his pregnant second wife Nicole Brydon Bloom braved the blizzard that dumped 16-19 inches of snow on New York City on Sunday in order to walk their Pit Bull Kuma.

The 54-year-old Fallout actor - who boasts 1.5 million Instagram followers - posted a question mark bubble gif over the head of his beloved canine companion as he leaped in the air for one snap.

Theroux famously adopted the female dog - whose name means 'bear' in Japanese - from Austin Pets Alive in the aftermath of Hurricane Harvey in 2018.

The expecting 31-year-old also shared footage of their snow day in Washington Square Park, which features a 77ft tall arch commemorating the centennial of President George Washington's 1789 inauguration.

On March 15, the first-time parents - who have a 23-year age gap - will celebrate their first wedding anniversary.

Last Tuesday, Bloom posted a video from their intimate baby shower held at NoHo cocktail bar - Jac's on Bond - which revealed a sonogram of their future child.

'It's going really well. I feel good,' the Paradise star told People last month.

'I was sick in the first trimester, so that was a bummer, but the second trimester has been going really well. I feel very lucky and grateful for that.'

Bloom added: 'I have the most adorable little niece, and so my twin sister Christine has been really helpful with advice and baby stuff, and obviously simultaneously preparing for season two of Paradise to come out. It's a good work-life balance at the moment.'

It's unclear how the May-December duo originally met, but they were first spotted canoodling at a Netflix event three years ago.

'I want all of my relationships to exist within the four walls of whatever room we're in,' Theroux told Esquire at the time.

'Having been in a public relationship, it's much more fun not being in a public relationship.'

The two-time Emmy-winning producer was referring to his famous ex-wife Jennifer Aniston as they ended their two-year marriage in 2017, which might have never been legal - according to TMZ.

Theroux was still living with his 'blindsided' girlfriend of 14 years - costume designer Heidi Bivens - when he met the 57-year-old Friends alum in 2007 and they went on to co-star in Wanderlust in 2011.

Bloom reprised her role as Agent Jane Driscoll in the second season of Paradise, which premieres Monday night on Hulu.

Dan Fogelman's post-apocalyptic political thriller also stars Sterling K. Brown, Shailene Woodley, Julianne Nicholson, Sarah Shahi, Aliyah Mastin, Percy Daggs IV and James Marsden.

And last July, HBO renewed Julian Fellowes' historical drama The Gilded Age for a fourth season, so fans can expect the Actor Awards nominee to reprise her role as wealthy socialite Maud Beaton.

Meanwhile, the Washington, D.C.-born actor will soon head to Texas to attend the world premiere of Victoria Strouse's sibling cult comedy Seekers of Infinite Love on March 12 during the SXSW Festival in Austin.

Theroux also plays Emily Blunt's onscreen husband in David Frankel's heavily-anticipated sequel The Devil Wears Prada 2 - hitting US/UK theaters May 1 - alongside Meryl Streep, Anne Hathaway and Stanley Tucci.

It's been nearly a year since Netflix's basketball comedy Running Point was renewed for a second season, but fans should expect the Luxury Collection brand ambassador to reprise his role as Kate Hudson's onscreen brother Cam Gordon.

Last May, Amazon Prime Video renewed Graham Wagner and Geneva Robertson-Dworet's post-apocalyptic drama Fallout for a third season, so fans can also expect Theroux to reprise his role as RobCo Industries CEO Robert Edwin House.

The Actor Award nominee's other upcoming roles include CIA case officer Van Spencer in Amma Asante's Cold War thriller Billion Dollar Spy, and casino mogul Steve Wynn in the Apple TV+ Siegfried & Roy biopic Wild Things.
