Hollywood breakups are usually messy, but David Harbour’s split from Lily Allen felt like a slow-motion car crash that everyone saw coming yet no one quite expected to end like this. By the time the news of their December 2024 separation hit the wires, the internet was already whispering about a new name: Ellie Beers Fallon.
Honestly, the timeline is where things get sticky.
People want to know if David Harbour just moved on fast or if there was an overlap. You've probably seen the headlines. The 27-year-old model became a focal point for fans trying to piece together why the Stranger Things star and the British pop icon called it quits after four years. It wasn't just about a new romance; it was about a specific photo of a cigar that seemingly broke Lily Allen’s heart.
Who is Ellie Beers Fallon anyway?
Before she was "David Harbour’s rumored girlfriend," Ellie Beers Fallon was mostly under the radar. She’s a New York-based model and aspiring actress. At 27, she’s significantly younger than Harbour, who turned 50 in 2025. That 22-year age gap definitely raised some eyebrows, but in Hollywood, that’s basically a Tuesday.

Ellie isn't a massive influencer with millions of followers. In early 2025, her Instagram sat around 10,000 to 11,000 followers. She keeps things pretty private, which, of course, only made people more curious. She’s been compared to a young Danniella Westbrook—that 90s British star vibe—and she has this classic, slightly edgy aesthetic.
The Atlanta Connection and the Cigar Photo
Most people believe the two met in Atlanta. While Harbour was busy filming the fifth and final season of Stranger Things, he was living in Georgia for a good chunk of 2024. This is where the detective work started.
In October 2024—months before Harbour and Allen officially split—Ellie posted a photo of herself smoking a cigar. On the surface? Just a girl and a stogie. But eagle-eyed fans (and allegedly Lily Allen herself) noticed the brand. It was one of David’s favorites.

That’s the kind of detail that turns a random Instagram post into a smoking gun. Sources close to Allen suggest she was "gutted" by that specific image, convinced it meant the romance started while she and David were still trying to make their marriage work.
Why people think there was an overlap:
- The Cigar Post: October 2024 photo in Atlanta with David’s preferred brand.
- Raya Rumors: Reports that Lily Allen caught David on the dating app Raya before the split.
- The India Trip: They rang in the 2025 New Year together in the Himalayas. That’s a pretty big "first date" trip if you only just met in December.
The Fallout with Lily Allen
Lily Allen hasn't exactly been quiet about her feelings, though she’s been artistic about it. Her album West End Girl, released in late 2025, is a raw, unapologetic look at the breakdown of her marriage. She’s referred to the project as "autofiction," but fans aren't stupid. They know who the songs are about.
She’s spoken on her podcast, Miss Me?, about the "emotional turmoil" that led her to check into a trauma treatment center shortly after the breakup. It sounds like she was doing some serious "Wagatha Christie" style investigating—reportedly cross-referencing women David followed on Instagram with profiles she found on Raya.
Despite the drama, there's a weirdly wholesome twist. Harbour was a stepdad to Lily’s daughters, Ethel and Marnie, for years. Even as the divorce moved forward, he was spotted taking the girls to Universal Studios in late 2025. Lily admitted in interviews that she "stays out of it," but the kids and David still text. It's a complicated, modern family mess.
Where do David and Ellie stand now?
The "Ellie and David" era might have been a flash in the pan. By March 2025, reports surfaced that the couple had split. Why? Apparently, the "unnecessary hate" and intense online scrutiny Ellie faced from fans was too much. Being the "other woman" in the court of public opinion is a brutal gig, especially when you’re up against a fanbase as protective as Lily Allen’s.
Since then, Harbour has been seen out and about—most recently linked to a woman named Morgan Cozzi in late 2025—but he hasn't confirmed a serious relationship. He seems to be leaning into his "gruff but loving" persona while wrapping up his tenure as Jim Hopper.
The Bottom Line
What most people get wrong is thinking this was a simple case of "out with the old, in with the new." It was likely a symptom of a marriage that had been struggling with distance and communication for a long time. David was in Atlanta; Lily was often in London or New York. Absence doesn't always make the heart grow fonder; sometimes it just makes room for someone else.
If you’re following this story, keep an eye on these specific markers for the truth:
- Social Media Breadcrumbs: Celebrity relationships in 2026 are won and lost in the "followed" lists and background details of photos.
- Lily’s Lyrics: West End Girl is essentially a diary. If you want the real dirt on what happened in those final months, the answers are in the liner notes.
- Public Appearances: Watch who David brings to the Stranger Things Season 5 premiere. That will be the definitive statement on his relationship status.
Ultimately, the Ellie Fallon chapter was a messy bridge between a high-profile marriage and whatever comes next for David Harbour. It’s a reminder that even "dad of the year" TV stars have complicated personal lives that don't always fit the script.
