David Harbour's Rumored Feud With Stranger Things Co-Star Won't Help His Soured Reputation

With less than a month to go before part one of the Season 5 finale of "Stranger Things" premieres on Netflix, one of its main stars found himself in hot water with a co-star. David Harbour, who plays Jim Hopper on the beloved series, was accused of harassment and bullying by Millie Bobby Brown, aka Eleven, Hopper's adopted daughter. The characters' relationship onscreen has always been somewhat cantankerous, and it seems to have continued offscreen between Harbour and Brown.

A source at the Daily Mail had the scoop on the allegations. "Millie Bobby Brown filed a harassment and bullying claim before they started shooting the last season," they said. "There were pages and pages of accusations. The investigation went on for months." None of the accusations were sexual in nature. The outlet admitted to not knowing what became of the claim, but apparently Harbour's estranged wife, Lily Allen, stood by him during it all.

Online opinions on the situation were mixed, with many siding with Brown, while others immediately assumed the claims were untrue. Shortly after the news dropped, an interview Brown did with MTV in 2024 resurfaced, with Brown looking slightly uncomfortable when interviewer Josh Horowitz joked that Harbour should officiate her wedding to Jake Bongiovi. "I don't know how I feel [about that]," she said, before suggesting that co-star Matthew Modine should do it — which he actually did. 

The accusations from Millie Bobby Brown were only the latest in a slew of bad press stories about David Harbour. A week before Halloween 2025, Lily Allen hinted on her "West End Girl" album that Harbour cheated on her. On the track "Dallas Major," Allen sings, "I probably should explain/How my marriage has been opened since my husband went astray." That was just one of the many implicit cheating references made on the album. In an interview with Perfect Magazine, Allen confessed, "There are definitely some things that happened in my real life that are reflected on this record."

Moreover, another tragic story resurfaced involving Harbour. Before he was married to Allen, Harbour allowed Christin Croft to stay at his apartment in NYC while he was working in Canada. "She was in the shelter system. I was trying to help her out," Harbour told New York Daily News back in 2015. Unfortunately, Croft committed suicide by jumping out of his apartment window, leaving a note.

While Harbour wasn't involved in what happened to Croft, netizens still felt the need to dredge it back up, given the PR nightmare Harbour had found himself in. "Bad week to be David Harbour," one person posted to X (formerly Twitter). "He better hope that Season 5 paycheck lasts long, cause he's not getting jobs anytime soon."
