Stranger Things star David Harbour has broken his silence on his ex Lily Allen’s 2025 album West End Girl.

Harbour, 51, has kept mum since the British singer and actor, 41, released the record — her first in seven years — after the 2024 breakdown of their five-year marriage.

Speaking about the album in a new interview with Variety , Harbor said: “It was weird.”

“I do believe that it is the privilege of every artist to use their experience to create art, and so I respect her for doing that,” he added.

“I can’t really say that much more because it’s my private life. In spite of the fact that a lot of people don’t allow me a private life — I value it. And I also value the lives of the people that I interact with privately. I just won’t speak about that.”

When asked if he wanted to respond to any of the claims made on the album, Harbour said: “Stories are complex and that’s why I say I respect her creation of art to channel her experience. It wasn’t my experience.”

Upon its release in October, the album was described by Allen as “a mixture of fact and fiction which I hope serves as a reminder of how stoic yet also how frail we humans can be.”

The album covers many themes, including cheating, gaslighting, open relationships and sex addiction.

In a five-star review, The Independent’s Hannah Ewens wrote: “It’s not just confessional pop, it’s obliterative; an emotional post-mortem carried out in public, a death-by-a-million-cuts account of a thoroughly modern marriage breakdown.”

Harbour and Allen married in 2019 after meeting on the dating app Raya, an exclusive dating app popular among celebrities and other high-profile figures.

Following their split, Allen decided to enter a treatment facility at the start of 2025, telling British Vogue in October 2025: “The feelings of despair that I was experiencing were so strong,” she told the outlet, adding that it was the closest she had come to relapsing after six years of sobriety.

“I’ve been into those places before against my will, and I feel like that’s progress in itself,” Allen continued. “That’s strength. I knew that the things I was feeling were too extreme to be able to manage, and I was like, ‘I need some time away.’”

Harbour, meanwhile, admitted in the new Variety interview to suffering a nervous breakdown this past December, forcing him to miss celebrations around the final season of Stranger Things.

“I do suffer from some confusing stuff — it’s confusing as hell,” he told the outlet. “I think a lot of people have a friend or a brother or a co-worker that deals with mental health stuff, and they’re probably pretty confused when that person gets depressed or gets manic or has an episode.”

He continued: “Under times of extreme stress, that can cause somewhat erratic behavior, and it’s embarrassing, and I’m ashamed of it. It’s not something I choose, and I wouldn’t wish it on my worst enemy.”
