**Millie Bobby Brown Accuses David Harbour of Bullying and Harassment During *Stranger Things* Season 5 Filming**
Stranger Things star Millie Bobby Brown has reportedly accused her co-star David Harbour of bullying and harassment during the filming of the show’s highly anticipated fifth and final season.
According to a report by RadarOnline.com, the 21-year-old actor filed a formal complaint against Harbour with Netflix, triggering an internal investigation. While details of the investigation’s outcome have not been disclosed, sources close to the production have confirmed that the accusations did not involve sexual misconduct.
David Harbour, who separated from singer Lily Allen in February 2025 after four years of marriage (as confirmed by *People* magazine), plays former police chief Jim Hopper in the show. He is the father figure to Millie Bobby Brown’s character. Harbour has not publicly commented on the allegations.
An insider told RadarOnline that the complaint was extensive and led to months of internal review. “Millie Bobby Brown filed a harassment and bullying claim before they started shooting the last season. There were pages and pages of accusations. The investigation went on for months,” the source explained.
Despite the controversy, Netflix has chosen not to make a public statement regarding the internal proceedings. Insiders emphasize that the streaming giant is determined to protect the show’s legacy and maintain focus on its much-awaited conclusion.
“It will be a theatrical event. Nothing is going to overshadow this, not even the leading man’s private life,” a source said.

### Behind the Scenes Tensions Ahead of *Stranger Things* Season 5 Release
As anticipation builds for the release of *Stranger Things* Season 5, reports suggest underlying tensions involving Millie Bobby Brown and David Harbour.
Since its debut in 2016, *Stranger Things* has played a pivotal role in transforming Netflix from a streaming underdog into one of Hollywood’s most influential studios. The show also turned Millie Bobby Brown from a little-known teen actor into a global star reportedly worth $50 million (£38 million).
According to a *Daily Mail* report dated November 1, 2025, after Brown allegedly lodged a formal complaint against Harbour regarding his behavior, she reportedly had a personal representative by her side throughout the filming of the final season.
Additionally, the fifth and final season of the hit Netflix series is being released in two parts. The first half was set to premiere later in the month, followed by the second part over Christmas. The much-anticipated finale is expected to debut simultaneously in cinemas and on Netflix on December 31.
Netflix had reportedly been counting on *Stranger Things* Season 5 to become one of its biggest global streaming events. However, a Netflix insider commented that the allegations and ensuing publicity surrounding David Harbour have overshadowed the show’s celebratory final chapter.
“It’s unfortunate that Mr. Harbour’s personal woes have hit the headlines at a time when *Stranger Things* fans were looking forward to a global celebration to mark the end of the groundbreaking show,” said a Netflix source.
Another source close to the production highlighted the weight of Netflix’s silence regarding Millie Bobby Brown’s allegations, suggesting it speaks volumes.
“Netflix will never comment on an internal investigation, but the fact they’ve not denied it speaks volumes. *Stranger Things* helped put Netflix on the map. Millions of fans around the world have been anticipating the finale. No one wants anything to take attention away from that.”

### David Harbour and Lily Allen’s Relationship Under Renewed Scrutiny Amid Allegations
As Netflix investigates Millie Bobby Brown’s reported complaint against David Harbour, the actor’s personal life has also come under renewed public scrutiny.
David Harbour, who had been estranged from his wife Lily Allen since earlier this year, faced ongoing speculation about infidelity following the release of Allen’s latest album, *West End Girl*. While the album received great reviews, it also delved into themes of heartbreak and betrayal, fueling rumors about the couple’s strained relationship and separation.
On October 26, the *Daily Mail* revealed that New Orleans costume designer Natalie Tippett was allegedly the “Madeline” referenced in one of Allen’s songs. The track reportedly included real text message exchanges between Allen and the woman Harbour was said to have had an affair with.
Although Allen did not deny the story, she later appeared to temper its implications. She explained that “Madeline” was not based on a single individual but rather a composite of several women Harbour was rumored to have been involved with.
A source close to the singer told *Daily Mail* that Allen had experienced significant emotional distress during the period of their separation and had channeled much of that turmoil into her music.
Explaining the personal struggle behind her creative process, the insider said, “Lily went through a lot of pain in private. There were a lot of tears, a lot of angst. She created some of her best art out of that pain.”
The source emphasized that despite the heartbreak, Allen had moved on from that dark period and was now focused on positivity and creative fulfillment.
“She’s in a great place now and not seeking revenge. She’s really happy and delighted with her fans’ response to the album,” the source added.
Another insider close to the couple noted that Allen faced an especially difficult time while David Harbour was under investigation by Netflix following Millie Bobby Brown’s complaint. Despite the tension surrounding the inquiry, she reportedly chose to stand by her estranged husband.
“Lily supported him throughout it all. It was a brutal time,” the insider said.
