Why Will Arnett, Carolyn Murphy’s love story ended after just months?

Will Arnett and Carolyn Murphy have reportedly called time on their romance after less than a year together, with reports suggesting the couple split “a few months ago”.

The news was first claimed by TMZ, and fans had already begun speculating something was amiss after 1990s supermodel Carolyn was noticeably absent when the 55-year-old actor attended the Oscars on March 15.

The pair only went public with their relationship in September 2025 after being introduced by a mutual friend, and at the time, Will couldn’t hide his admiration for the model. 

Speaking shortly after they got together, he described their connection as effortless, saying there was “an ease from the moment” they started spending time together. 

He also praised the 52-year-old model as “generous of spirit”, adding that it was one of many things he loved about her.

Their relationship had appeared to be going strong, with the couple even making a cosy appearance in London last year, attending Sean Hayes’ stage show Good Night, Oscar, alongside friends.

However, things now appear to have quietly fizzled out. 

Neither Arrested Development star nor Carolyn has publicly commented on the split.

The breakup follows Will’s previous high-profile relationships, including his five-year romance with businesswoman Alessandra Brawn, with whom he shares a young son. 

He also has two teenage sons from his marriage to actress Amy Poehler, with whom he remains on good terms.

Carolyn, meanwhile, shares an adult daughter with ex-husband Jake Schroeder.

Despite their split, Is This Thing On? actor has often spoken warmly about Amy in recent interviews, praising her as a strong co-parent and saying he feels “lucky” to still have her support in raising their children.
