Millie Bobby Brown Alleges Harassment Against David Harbour After Ex’s Cheating Claims

Stranger Things actor David Harbour faces a tumultuous situation as Millie Bobby Brown and Lily Allen both publicly address accusations against him. Brown, who stars alongside Harbour in the series, has lodged complaints just as the show’s fifth and final season approaches.

According to reports, Millie Bobby Brown, 21, has formally accused Harbour of bullying and harassment, leading to an internal investigation prior to the start of filming the final season. Her complaint allegedly includes extensive documentation of various allegations.

Sources reveal that “there were pages and pages of accusations,” and while the specifics of the findings remain confidential, it’s reported that there were no claims of sexual misconduct involved. Netflix has not issued any public comment regarding the situation.

In a related development, Lily Allen, Harbour’s ex-wife, had shown him support during this challenging period. Sources have characterized the time as “brutal” for the actor.

Lily Allen’s Accusations

On October 24, 2025, Lily Allen released her album West End Girl, which touches on themes of betrayal and infidelity experienced during her marriage to Harbour.

In this album, Allen suggests Harbour’s infidelity through several tracks, reportedly referencing Natalie Tippett, a costume designer from the 2021 movie We Have a Ghost.

Allen’s lyrics hint at the heartbreak she faced, mentioning cheating and intricate marital rules. In interviews, she has made statements about Harbour’s alleged “sex addiction” while clarifying that not all lyrics are strictly factual; some represent composite experiences from their marriage.

What’s Next for the Case?

Amid this scandal, production on Stranger Things Season 5 is set to continue. The concluding episodes will premiere on December 25, leaving fans watching both on-screen and off-screen drama unfold.
