Lily Allen Bombshell: Did David Harbour’s Affair Push Her to the Brink?

Lily Allen has revealed she became suicidal after discovering that her husband, “Stranger Things” star David Harbour, had been having a three-year affair. The British singer, 39, spoke candidly in a new interview with British Vogue, saying the betrayal brought her dangerously close to relapsing into alcohol and drug use and left her battling a severe eating disorder.

Allen ended her relationship with Harbour, 50, in December 2024 after learning of his infidelity. The couple, who married in Las Vegas in 2020, had lived together in Brooklyn with Allen’s two daughters from her previous marriage. The singer said the emotional fallout from the affair left her “wanting to die” and forced her to check herself into a residential treatment facility.

Lily Allen Opens Up About Despair After David Harbour’s Affair

Speaking to British Vogue, Allen said the period following her split from Harbour was one of the darkest of her life. “The feelings of despair that I was experiencing were so strong,” she explained. “The last time I felt anything like that, drugs and alcohol were my way out, so it was excruciating to sit with those feelings and not use them.”

Allen, who has been sober for six years, admitted she “came close” to relapsing and developed a “really, really bad problem with food.” Recognizing that she was in crisis, she chose to admit herself to a treatment facility — a decision she called an act of strength and self-awareness. “I knew the things I was feeling were too extreme to manage,” she said. “I needed some time away.”

The betrayal reportedly came to light after Allen discovered Harbour had a secret profile on the celebrity dating app Raya — the same app where they first met. She joined the app herself, posing as someone looking for women, and found Harbour active on the platform for at least a month.

Allen shared that her upcoming album, set for release later this autumn, is deeply influenced by the turmoil of her marriage’s breakdown. Lyrics from her new songs hint at betrayal and self-reflection. In one track, “Sleepwalking,” she sings: “You let me think it was me in my head and nothing to do with them girls in your bed.” Another song, “Dallas Major,” refers to how their marriage “has been open since my husband went astray.”

From Heartbreak to Healing: Lily Allen’s Path Forward

Despite the heartbreak, Allen said she now feels “OK” and is focused on recovery. She has returned to daily sobriety meetings, meditation, therapy, and is taking antidepressants. “There are good and bad days,” she admitted, but said she is committed to showing her daughters that they can overcome adversity together.

Reflecting on the marriage, Allen acknowledged that “there were lots of good things” about their time together, including the experience of living in the United States with her children. Still, the end of the relationship prompted significant changes. She has since purchased a flat in London, throwing herself into decorating as a way to cope with her grief.

Allen also spoke about the challenges of dating in her 40s and the impact of technology on modern relationships. “The abundance of opportunity the internet has created and the ease with which people are available — that’s what happened,” she said.

Her deeply personal new music follows a career-long pattern of drawing from her most traumatic experiences. “My first album was about the breakup of my first love. My second was about the trauma of fame. ‘Sheezus’ came when I had two children and didn’t fit into that world. My last album was about emerging from my first marriage. We’ll see what happens with these songs.”

As Allen prepares to release her new album, her candid reflections offer a raw look into how betrayal, addiction, and resilience have shaped her life — and how she is determined to rebuild it on her own terms.
