Who Has David Harbour Dated? From Ex-Wife Lily Allen and Julia Stiles to Post‑Breakup Sightings with Ellie Beers Fallon

In 2025, few celebrity stories have captured cultural attention quite like Lily Allen’s breakup album West End Girl, a deeply confessional LP that drew global conversation about love, loss and artistic expression. At the centre of that narrative was Allen’s separation from Stranger Things star David Harbour — a split that prompted intense curiosity not just about the music, but about the real‑life relationships behind it.

Amid the lyrical speculation and fan debate over song characters like “Madeline,” one question kept coming up in search engines worldwide: Who has David Harbour dated? The answer is a story that spans decades, from early partnerships with fellow actors to a high‑profile marriage with Allen and recent reported sightings with a younger companion.

Maria Thayer

Before Harbour became a household name, he was linked romantically to actress Maria Thayer in the late 2000s. Known for her roles in Forgetting Sarah Marshall and Strangers with Candy, Thayer reportedly dated Harbour from around 2009 to 2011. Some media at the time suggested a brief engagement, though neither party confirmed this publicly. Their relationship was kept largely out of the spotlight, reflecting how Harbour navigated early romance with discretion long before Stranger Things catapulted him into global fame.

Julia Stiles

From approximately 2011 to 2015, David Harbour was in a long‑term relationship with actress Julia Stiles, best known for 10 Things I Hate About You and Dexter’s Jordan Chase. The pair lived together in New York and maintained a partnership that lasted four years. Despite their public professions, they rarely spoke about their relationship, choosing instead to let their work take centre stage. Their amicable split left little sensational trace, and both went on to pursue their careers with privacy intact.

Alison Sudol

In 2018 and 2019, Harbour dated actress and musician Alison Sudol — also known by her former stage name A Fine Frenzy. Their relationship was one of the more visible on Harbour’s timeline, with Sudol accompanying him to events like the Critics’ Choice Awards, where their chemistry was noted by industry observers.

She recently shared a post on Instagram, which some netizens have claimed to have been about her ex, Harbour. The post was liked by Lily Allen.

Lily Allen

One of Harbour’s most public relationships began in early 2019 with British singer‑songwriter Lily Allen. The two met on the celebrity dating app Raya and quickly formed a connection that led to marriage the following year. Their union included shared family life with Allen’s children and joint red‑carpet appearances — most memorably at the 2020 SAG Awards.

Their 2024–2025 divorce became part of the cultural conversation when Allen’s West End Girl confronted emotional themes tied to fidelity, betrayal and narrative ownership. While Harbour has largely refrained from engaging with the specifics of lyrics or rumours, the separation undeniably brought renewed mainstream scrutiny to the timelines of their relationship. Notably, a woman identified in some press as the real‑world “Madeline” — central to public theories about the album — publicly denied those claims, underscoring the complexity of separating public storytelling from personal experience.

Ellie Beers Fallon: Reported Post‑Split Sightings

Since his split from Allen, Harbour has been seen in the company of model Ellie Beers Fallon, a New York–based aspiring model in her 20s. Photographs and sightings in early 2025 — including joint travel around New Year’s Eve in the Himalayas and multiple appearances during Harbour’s work in Georgia — have fuelled speculation about a possible romantic connection. Neither Harbour nor Fallon has publicly confirmed the nature of their relationship, but the repeated sighting together suggests a chapter that many fans are watching closely.
