Will Arnett and Carolyn Murphy have reportedly split.

The couple broke up "a few months ago", TMZ has claimed.

It comes after 1990s supermodel Carolyn, 52, did not attend the Oscars with the Is Thing Thing On? actor Will, 55, on March 15.

The pair had been dating since September 2025 after they were "set up" by a mutual friend, and two months later, Will said that the natural connection between them makes their romance work.

He told People: "I think that there's just an ease from the moment that we started hanging out.

"We have a real ease with each other, and she's just such a generous-of-spirit person, and that's what I love. One of the many things that I love about her."

Last September , Will stepped out with the blonde bombshell in London to see 55-year-old actor Sean Hayes' play Good Night, Oscar.

Sean posted a photo of himself, 56-year-old husband, musical composer Scott Icenogle, Will, and Carolyn backstage at the production, and captioned the Instagram upload: "Another recent surprise visit from one of the greats. Love you, Willie.[heart emoji] #GoodNightOscar (sic)."

Carolyn and Will's relationship followed his split from long-time girlfriend, businesswoman Alessandra Brawn, in 2024 after five years together.

Carolyn, meanwhile, was previously married to Jake Schroeder from 1999 to 2002, and they have a 25-year-old daughter named Dylan together.

Will has a five-year-old son called Denny with Alessandra, and a source told People that "they remain committed co-parents".

The Twisted Metal star also has sons Archie, 16, and Abel, 15, with his ex-wife, Amy Poehler.

Will and the 54-year-old comedienne became the beloved comedy power couple when they got married in 2003, but they split in 2012 and finalised their divorce in 2016. They remain close.

In April 2025, Amy appeared on the SmartLess podcast, which her ex-husband presents with Sean Hayes and 57-year-old Jason Bateman, and Will praised the Inside Out actress for being a great mom.

He said: "I have to try really hard, but Amy, you're really good at this, and you help me do this in concert with you, to remember to listen to what they're saying and to not try to impose what I think, 'You need this, you need that.'

"To actually sit and listen to what your kid is trying to say. Encourage them to, as much as they can, to speak. I don't come by it naturally because that's not how I was raised."

He also praised their continuing co-parenting relationship.

He said: "I am really proud of it. Of course, things take a minute because everybody is sort of adjusting to what it is.

"I'm also very proud of, certainly as parents, what we've been able to do. That has been really important to both of us. 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. I feel really lucky.

"She's the person that I go like, 'Hey, I'm thinking about doing this.' Whether it's life or work and I really seek her counsel because it's important to me because I trust her. She's awesome."
