Jennifer Aniston's ex Justin Theroux, 52, bares muscled arms during rare sighting with girlfriend Nicole Brydon Bloom, 29, in NYC

Justin Theroux, 52, cut a characteristically dashing figure while out with his girlfriend Nicole Brydon Bloom, 29, in New York this week. 

The ex-husband of Jennifer Aniston was a smoldering sensation in a tank top that bared his musclebound arms and fell flatteringly over his toned torso.

His outfit emphasized his youthfully fit physique to full advantage as he sauntered down the street, walking his bicycle next to his girlfriend.

Justin and Nicole were first spotted together in February of this year, and have only infrequently surfaced in public as a couple ever since.

He and Jennifer were married from 2015 until 2017 but managed to stay friendly after what Justin has called a 'gentle separation.'

When he was spotted with Nicole in New York this week, Justin slid his toned legs into a clinging pair of dark jeans and slung a set of earbuds across his shoulders.

Amid the soaring temperatures of the New York summer, he lent himself a bit of shade with a baseball cap and a gleaming pair of colorful shades.

Meanwhile Nicole, an actress known for Downton Abbey creator Julian Fellowes' new show The Gilded Age, was similarly casually attired.

She strutted her stuff down the street in a plunging sleeveless top and a high-waisted pair of matching shorts, letting her silky dark hair fly free in the breeze.

Nicole and Justin reached a milestone last December when he accompanied her as her date to her twin sister Chrissy's wedding.

Nicole snapped a mirror selfie from the festivities that showed her and Justin beaming on a staircase amid a claque of loved ones including his dog Kuma.

Since their first public sighting in February 2023, Justin and Nicole have only been intermittently spotted in public, including one night last August when they were glimpsed kissing after a night out on the town.

Just before the lip-lock, they had enjoyed an evening at Ray's, the New York dive bar that Justin owns with some friends including Succession actor Nicholas Braun.

Justin also enjoys a famously amicable relationship with his ex-wife Jennifer Aniston, whom he was with for a total of seven years.

They announced their split in February 2018, and a few months later Justin told the New York Times how amicable the process had been.

'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.' 

The Tropic Thunder writer added: 'In a weird way, just sort of navigating the inevitable perception of it is the exhausting part.'

Justin, who is three years younger than Jennifer, married her in Bel-Air in 2015 and they broke up about two years later.

Jennifer and Justin first started dating in 2011, having worked together on the film Wanderlust. He had carried on a 14-year relationship with costume designer Heidi Bivens that collapsed in 2011. 

At the time, a friend of Heidi's told E! News claimed that Heidi had been 'straight-up dumped,' though the outlet made sure to qualify: 'Not to say it's Aniston's fault, maybe the timing was just terrible?'

A source in Justin's camp insisted to Page Six: 'Things were already over between him and Heidi before he got close to Jen.'

Heidi's mother Marilyn spoke to Radar Online in 2016, claiming that Justin initially tried to persuade Heidi he and Jennifer were not an item.

Marilyn asserted: 'Heidi told me what Justin had told her, that something was going to be written about him and Jennifer, that something was going on between them and he wanted her to know that it was nothing, there was nothing to it.' 

In Marilyn's telling, Heidi allegedly ultimately discovered that the rumors were true, '[a]nd my sweet Heidi she calls me and says: "Oh mommy." I was going through cancer at the time. It was a time that hurt our family.'
