All About Natasha Lyonne’s Boyfriend, Bryn Mooser

Actress Natasha Lyonne famously dated comedian Fred Armisen for a number of years, but fewer people know about her current relationship with media executive Bryn Mooser. The Russian Doll actress has been romantically linked to Mooser since 2023, soon after she admitted she and Armisen had split.

While speaking with The Hollywood Reporter in October of that year, Lyonne confirmed the break up when she was asked about whether she still lived in Los Angeles.

“I’m not. I had been there living with Fred and during COVID,” she replied, before joking, “I honestly think we broke up because I wanted a swimming pool.”

More seriously, she added, “We love each other just about as much as two people can love each other and we’re still talking all the time. But Freddy doesn’t like a swimming pool. It might seem like a mundane reason for a breakup, but during that pandemic, you’ve got to get your laps—I’m like Burt Lancaster in The Swimmer...So that’s the real scandal. I guess I finally am an actual bicoastal.”

Here’s everything we know about Bryn Mooser and his relationship with Lyonne so far.

Bryn Mooser is known as a director and producer, but also a business mogul, especially in regards to media companies. The 45-year-old co-founded Ryot, which focuses on documentaries with virtual and augmented reality, according to his IMDb page. He sold the company to Verizon in 2016, then launched another film and TV studio in 2019, XTR, which also focuses on non-fiction content. He became the CEO of Documentary+ in 2020, per SCMP.

Mooser’s documentary Body Team 12 won him an Emmy in 2015 and an Oscar nomination for producing. In 2019, he was nominated at the Oscars again for the documentary Lifeboat.

Mooser also launched A.I. animation company Asteria Film with Lyonne in 2022, which they both claim is ethically sourced A.I.

The pair knew of one another at least as early as 2022, in order to found their company. But rumors that Lyonne and Mooser were dating popped up in 2023, according to the Daily Mail. That was the year they started making appearances at red carpet events, including Macaulay Culkin’s Walk of Fame ceremony, followed by the 2024 Golden Globes, the 2025 Independent Spirit Awards, the SNL 50th Anniversary Special, the Chanel Pre-Oscar Awards Dinner, and Vanity Fair’s Golden Globe party.

At the ISAs, Lyonne told photographers, “I think I will take a boyfriend picture, thank you so much,” inviting Moser to pose with her.
