Will Arnett Alessandra Brawn Split: What Really Happened

Hollywood breakups usually come with a side of dramatic Instagram deletes or cryptic PR statements that say a whole lot of nothing. But the Will Arnett Alessandra Brawn split didn't follow that script. Honestly, it was so quiet that by the time people realized they weren't a thing anymore, Will was already walking red carpets with someone else.

If you've been following the SmartLess host, you know he’s pretty private about his personal life despite having one of the most recognizable voices on the planet. He and Alessandra Brawn, a high-flying fashion executive and former PR maven, seemed like a solid match. They were together for roughly five years. They have a son. They lived that high-end, low-profile life that most celebrities dream of pulling off. Then, things just... stopped.

No fireworks. No messy tabloid wars. Just a quiet shift in the timeline.

When did the Will Arnett Alessandra Brawn split actually happen?

Most people didn't even notice the cracks until late 2024. For a long time, the two were a staple at big events, like the Creative Arts Emmys where they first went public in 2019. But as 2024 rolled on, the joint appearances dried up.

According to sources close to the situation—and later confirmed by major outlets like People—the pair actually called it quits toward the end of 2024. It wasn't some sudden explosion. It sounds like they just reached the end of their road as a romantic couple. By the time 2025 kicked off, the move was official, even if the public was still catching up.

Basically, they did the "conscious uncoupling" thing without actually using that annoying phrase. They’ve both moved on, but because they share a son named Denny, they’re still very much in each other's orbits.

Co-parenting is the new priority

One thing you have to give Arnett credit for is how he handles his exes. Look at him and Amy Poehler. They’ve been divorced for years, but they’re famously good at co-parenting their two sons, Archie and Abel.

He’s reportedly taking that same approach here.

• The shared son: Denny is 5 now. Both parents are reportedly "committed co-parents."
• The blended family vibe: Brawn has a son, Nash, from her previous marriage to Jon Neidich. Arnett was a stepfather figure there for years.
• The move: There was a lot of chatter on Reddit about Will moving back to New York full-time around the time of the split.

While the romantic side of the Will Arnett Alessandra Brawn split is a done deal, the family side is still functioning. It’s mature. It’s boring in a good way. It's exactly what you want for the kids involved, even if it doesn't make for "spicy" headlines.

Who is Will Arnett dating now?

If you were wondering if Will was sitting around moping, the answer is a hard no. By August 2025, rumors started swirling that he’d found a "natural connection" with someone new.

Enter Carolyn Murphy.

She’s a legendary supermodel, an environmental advocate, and, at 51, she’s closer to Will’s age than some of his previous partners. They were set up by a mutual friend, which is kinda refreshing in the era of celebrity dating apps.

They made it "red carpet official" at the BFI London Film Festival in October 2025 for the premiere of his film Is This Thing On?. More recently, they were spotted looking incredibly cozy at the 2026 Golden Globes. Will even told reporters that what he loves most about Carolyn is her "generous spirit" and how easy everything feels between them.

The timeline of the transition

It’s easy to get the dates mixed up, so here is the rough sequence of how this all went down:

1. Late 2024: Will and Alessandra quietly split after five years.
2. Early 2025: Will is seen hanging out with friends like Gigi Hadid and Bradley Cooper, sparking minor rumors that he's back on the market.
3. August 2025: Will and Carolyn Murphy start dating after being set up.
4. September 2025: Major news outlets finally confirm the Will Arnett Alessandra Brawn split while simultaneously announcing his new relationship with Murphy.
5. January 2026: Will and Carolyn attend the Golden Globes as a settled, happy couple.

Why the split caught fans off guard

Most fans felt blindsided because Will doesn't talk about his personal drama on SmartLess. He’ll roast Jason Bateman for three hours, but he rarely mentions who he’s going home to.

Some eagle-eyed listeners on Reddit noticed he stopped mentioning "Lulu" (his nickname for Alessandra) in early 2024. That was the first clue. Then came the real estate moves—selling the house in LA and the quiet shift to the East Coast.

It’s a classic Hollywood move: if you don’t say anything, people might not notice for six months. By the time they do, the dust has already settled.

Actionable insights for fans and followers

If you're looking for the "why" behind the split, you probably won't get a tell-all interview. Arnett isn't that guy. But there are a few things we can take away from how this played out.

• Watch the social cues: In the age of digital footprints, "silence" is usually the loudest signal. When a celebrity stops mentioning a partner on a weekly podcast, the writing is usually on the wall.
• Respect the co-parenting boundary: Both Arnett and Brawn have kept the focus on their son, Denny. It’s a good reminder that just because a relationship ends doesn't mean the family unit disappears.
• Check the source: When news like this breaks, look to confirmed reports from 2025 rather than old 2024 speculation. The timeline of their breakup was backdated by several months once it finally hit the press.

The Will Arnett Alessandra Brawn split is effectively old news in their world, even if it’s still a hot topic for fans. Both have moved into new chapters, with Will seemingly very happy in his current relationship with Carolyn Murphy.

Keep an eye on the 2026 awards season—it looks like Will and Carolyn are going to be a frequent fixture on the circuit.
