Will Arnett Is Dating Carolyn Murphy, Quietly Split from Alessandra Brawn Last Year

September 6, 2025:  Actor and SmartLess podcast co-host Will Arnett (55) is officially dating supermodel and environmental advocate Carolyn Murphy (51), after quietly ending a years-long relationship with Alessandra Brawn last year.

The New Couple

Arnett and Murphy were recently seen together in London, where they attended a performance of Good Night, Oscar on the West End. A backstage photo posted by actor Sean Hayes showed the pair smiling alongside Hayes and his husband.

Murphy is renowned in the fashion world, having appeared on the cover of Vogue over 70 times and serving as a longtime ambassador for Estée Lauder. She also has a 24-year-old son, Dylan Blue.

A Quiet Separation

Arnett had been in a steady relationship with Alessandra Brawn—a former fashion CEO and PR executive—since 2019. The couple quietly split in late 2024 after five years together. They share a 5-year-old son named Denny, and sources say they continue to co-parent harmoniously.

Their final public appearance together was in September 2024. Since then, both have maintained low-key private lives, with Arnett prioritizing his roles as a father and professional.

Family and Career in Focus

In addition to Denny, Arnett is father to two teenage sons—Archie (16) and Abel (15)—from his previous marriage to comedian Amy Poehler. Despite their divorce, Arnett and Poehler continue to share a close and cooperative co-parenting dynamic, with Poehler recently appearing on his SmartLess podcast.

Professionally, Arnett remains active. His much-anticipated film Is This Thing On?, directed by Bradley Cooper, will premiere at the New York Film Festival on October 10, 2025, followed by a theatrical release in December. He also continues to co-host the popular SmartLess podcast.
