Lily Allen and David Harbour’s recent split seems to have taken a turn for the messy.

The “Smile” singer and “Stranger Things” actor reportedly separated in early 2025 after less than five years of marriage. On October 24, 2025, Allen released her first album in seven years, “West End Girl,” in which she seems to accuse her husband of cheating and crossing emotional lines in their marriage.

“Intimacy is inherently messy,” Allen told The Sunday Times of the album’s inspiration. “There are usually agreed-upon boundaries in relationships. But whether those boundaries are adhered to or not is becoming a grey area all of a sudden.”

Harbour later revealed to GQ that he met Allen on Raya, an exclusive celebrity-favored dating app, while he was filming Marvel’s “Black Widow” in London.

“I started texting with her, she was in Italy at the time — we got together, went on a date at the Wolseley, and it was, you know, she’s fucking unbelievable,” Harbour told GQ.

He also said he fell in love with her during their third date.

“I was just in this phase, where I was like, I’m just going to be brutally honest about everything, because why lie? And I told her something about my life, about my beliefs,” he said. “It would take a really extraordinary person to be accepting of the things that I said. And I remember thinking: Wow, that’s somebody I want to be around.”

She was like, ‘He’s not our dad! He’s not our dad!'”

“And then the younger one was like, ‘Well, what is he? He’s kind of our dad.’ She’s like, ‘No, he’s not, he’s our stepdad.’ And she goes, ‘What is he?’ And she goes, ‘He’s just some guy in our lives!'” Harbour continued.

“I now have a kids’ phone called Pinwheel,” Allen said. “It has no browsing capability and no social media, but you can still have Uber and Spotify.”

During an episode of her BBC Sounds podcast “Miss Me?,” Allen discussed sexual preferences with her cohost and friend, Miquita Oliver.

“I wonder if I kink-shame my husband,” she said. “Because he often quite asks for things, and I’m like, ‘No, babe, it’s not happening.'”

“I’m not like, ‘You piece of shit, how dare you ask me to do that!'” Allen added. “I’m just like, ‘Hmm, headache. Little headache, got a bit of a headache — maybe not tonight.'”

Asked how Harbour felt about the venture, Allen said, “He thinks it’s great.”

“At first, he was like, not turned on,” she continued, “but he was like, ‘Is this a kink for you?’ And I was like, ‘No, it’s totally not a kink,’ but maybe there’s something in the power element of it that’s slightly kinky for me.”

Allen later revealed that she wrote her breakup album, “West End Girl,” that same month during a 10-day creative burst.

“Nobody knew what was going on in my life,” Allen told The Sunday Times. “So I got into the studio, cried for two hours, and then said, ‘Let’s make some music.'”

On February 3, 2025, People reported that Allen and Harbour had separated.

“Her marriage has been crumbling, and they have split,” an anonymous source told the publication. Representatives for Allen and Harbour did not respond to requests for comment from People.

Shortly after, Allen revealed during an episode of “Miss Me?” that she’d recently spent a few weeks in a treatment center, receiving therapy for “emotional turmoil.”

“I needed some time and space away from everything. I did a lot of shadow work, lots of work about my inner child stuff,” she said.

“I’m not saying I’m 100% there,” she continued. “I’m not saying that I’m getting it 100% right or ever will. But I’m definitely in a stronger place.”

During an interview with GQ, Harbour refused to confirm or deny reports of his marriage ending.

“I’m protective of the people and the reality of my life,” he said. “There’s no use in that form of engaging [with tabloid news] because it’s all based on hysterical hyperbole.”

In “West End Girl,” Allen tells a brutal story of marital turmoil and betrayal, portraying her muse as an emotionally manipulative sex addict.

“Who said romance isn’t dead? Been no romance since we wed,” she sings in track three, “Sleepwalking.” In several other songs, including “Ruminating,” “Tennis,” and “4chan Stan,” she alludes to catching her husband being intimate with other women, crossing boundaries they’d agreed upon.

“We had an arrangement / Be discreet and don’t be blatant / There had to be payment / It had to be with strangers / But you’re not a stranger,” she sings in track five, “Madeline.” Two songs later, Allen seems to accuse Harbour of keeping a separate apartment in the West Village expressly for affairs, and describes finding sex toys and “hundreds” of condoms hidden there.

In interviews, Allen has described the album as semi-autobiographical. (She has also begun referring to Harbour as her ex-husband, per British Vogue, though no divorce filings have yet been made public.)

In the opening track on “West End Girl,” Allen recalls house-hunting in New York and buying an expensive brownstone with Harbour.

“Billy Cotton got sorted / All the furniture ordered,” she sings, name-checking the designer whom she hired to help decorate. “I could never afford this / You were pushing it forward / Made me feel a bit awkward.”

Just a few days after Allen’s album was released, the former couple’s Brooklyn home was put back on the market.

TMZ reported that the five-bedroom, four-bath brownstone was listed for just under $8 million.
