David Harbour has broken his eight-month silence on one of Hollywood’s most turbulent off-screen stories, telling Variety that Lily Allen’s scorching breakup album and a tabloid report alleging misconduct toward his Stranger Things co-star Millie Bobby Brown converged last autumn to trigger a serious mental health breakdown.
The timing was brutal. Allen released West End Girl in October 2025, one month before Stranger Things began airing its final season — turning what should have been a career victory lap into, by Harbour’s account, a frightening mental health emergency. Asked about the album, he offered measured words: “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 declined to go further, citing the value he places on his private life and the lives of those around him, saying only: “It wasn’t my experience.”
A week after the album dropped, the Daily Mail published a report claiming Brown had filed “pages and pages” of bullying and harassment claims against Harbour ahead of filming Stranger Things’ fifth season. Harbour called that report false and said its arrival in the same week as the Allen album was “weird.”
Harbour, who was diagnosed with bipolar disorder in his 20s following a manic episode, acknowledged the episode openly: “I had a breakdown.” He told Variety that stress can produce erratic behavior and that he finds it “embarrassing” and is “ashamed of it,” while noting how confusing such episodes are for the people closest to those experiencing them.
The breakdown caused him to miss the show’s wrap celebrations. But the picture he paints of his relationship with Brown today is the opposite of fractured. Brown, in an email to Variety, described the “gratitude” she feels for the collaboration, noting their work grew increasingly creative and emotionally demanding across the seasons. Harbour, meanwhile, let slip they are already developing multiple projects together: “You’ll see more of me and Millie — 10 years wasn’t enough.”
Harbour is currently promoting his acclaimed performance in the HBO miniseries DTF St. Louis, for which he won the Gotham TV Award for best supporting performance in a limited series and is considered an Emmy contender. Allen, now recovered from her own mental health struggles, is currently on tour supporting West End Girl through the fall.
