Will Arnett and Carolyn Murphy had a stylish date night at New York Fashion Week.

The Arrested Development alum, 55, and the supermodel, 51, were photographed arm-in-arm at a presentation for designer Jenni Kayne in New York City’s SoHo neighborhood on Friday, Sept. 12.

Arnett kept things casual, wearing jeans, a denim jacket, a white T-shirt and brown loafers, while Murphy stepped out in a black V-neck dress. She accessorized her look with a cheetah-print purse and black flats.

PEOPLE first reported that the pair were dating on Sept. 5.

The actor and Smartless podcast co-host quietly split from Alessandra Brawn, his girlfriend of five years, in late 2024, PEOPLE also reported. The pair share one child, a son named Alexander “Denny” Denison, and “remain committed co-parents,” a source said.

Arnett and Murphy made one of their first public appearances together when they stepped out late last month to see Sean Hayes‘ play, Good Night, Oscar, on London’s West End.

The couple posed backstage alongside Hayes, 55, and his husband, Scott Icenogle, in an Instagram photo posted by Hayes. “Another recent surprise visit from one of the greats. Love you, Willie. ❤️,” the Will & Grace star wrote.

Murphy, a longtime spokesmodel and brand ambassador for Estée Lauder who has graced the cover of Vogue more than 70 times, is mom to 24-year-old Dylan Blue and was previously married to Jake Schroeder from 1999 to 2002, per the Daily Mail.

Arnett and the Parks and Recreation star wed in 2003 — Poehler’s first marriage, and Arnett’s second, after a brief union with Penelope Ann Miller — and later split in 2012.

While Arnett is often extremely private about his romantic relationships, he has been candid about his love for being a dad — and feeling confident as a co-parent with Poehler, 53.

On an April episode of the SmartLess podcast — which Arnett co-hosts with Hayes and Jason Bateman — the actor acknowledged that although it took some time to get to where they are now, he’s proud of their relationship.

“I’m really, really lucky to have her as a partner in this way. There aren’t many people I speak to more than I speak to her, which is weird — you know what I mean? But it’s great,” Arnett said of Poehler. “She is somebody that I still run a lot of stuff by.”

“She’s the person I go to, like, ‘Hey, I’m thinking about doing this.’ Whether it’s life or work, I really seek her counsel because it’s important to me — because I trust her,” he continued. “She’s awesome.”
