David Harbour has spoken publicly about a mental health breakdown and the strain of his split from Lily Allen, in a new interview published in the US on 10 June 2026, as theStranger Thingsactor addressed the fallout from the couple's separation and the singer's albumWest End Girl.
Harbour, 51, said the pressure of the period left him ashamed of some of his behaviour, while also insisting that the details of his private life remained his own.
The news came after Allen releasedWest End Girllast autumn, a record widely read as an account of the collapse of the pair's marriage, and after months of speculation around Harbour's conduct both off set and in public. Harbour and Allen separated in 2024 after several years together, and the singer later channelled the split into music that drew intense attention for its personal detail.
Harbour told Variety that he had 'a breakdown' and described his long-running mental health struggles as confusing and, at times, embarrassing. He linked the episode to periods of extreme stress, saying that his condition could lead to erratic behaviour he does not choose and would not wish on anyone else.

He also said that some people's gifts and illnesses are bound up together, a remark that gives the interview its strange, unsettled pulse. It is not a neat or comforting explanation, but then mental health rarely is. Harbour said a sensitive nervous system can fuel the work he loves, yet also makes him behave 'a little weird' when pressure builds.
Harbour has spoken before about being diagnosed with bipolar disorder in his twenties, and he has previously described therapy and sobriety as central to managing it. The new interview does not mark a sudden revelation so much as a public acknowledgement that the past year knocked him sideways again.
Harbour was noticeably guarded about Allen herself. He did not go into the mechanics of the breakup, but he did callWest End Girl'weird,' while saying he respects an artist's right to turn personal pain into work.
That is the line, more or less, between private hurt and public storytelling, and Harbour made clear he did not want to cross it.
His comments arrive after Allen's own highly personal account of the split, which helped turn their marriage breakdown into tabloid catnip and, frankly, a rather ugly circus. Reports and interviews have suggested the album contains references to betrayal and emotional fallout, though Allen has also said the material should not be treated as literal gospel.
