Will Arnett adores his 1990s supermodel girlfriend Carolyn Murphy's "generous spirit".

The 55-year-old actor and the 51-year-old blonde beauty have been dating since September after they were "set up" by a mutual friend, and Will said the natural connection between the pair makes their romance work.

A very happy Will 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."

In September, People confirmed that Will and Carolyn are dating.

That month, the SmartLess podcaster stepped out with his new lover 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 upload with: "Another recent surprise visit from one of the greats. Love you, Willie.[heart emoji] #GoodNightOscar (sic)."

Their relationship follows the Twisted Metal actor's split from his long-time girlfriend, businesswoman Alessandra Brawn, in 2024 after five years together.

Carolyn 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 "they remain committed co-parents".

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

Will and the 54-year-old comedienne - who became the beloved comedy power couple when they got married in 2003 - divorced in 2016, but they remain close.

In April, Amy appeared on the SmartLess podcast - which her ex-husband presents with Sean Hayes and 56 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."

And Will is "really proud" of their co-parenting relationship.

He added: "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."
