Millie Bobby Brown and David Harbour Break the Silence: A Decade-Long Bond Stronger Than Rumors

Amid swirling reports and online speculation, the Stranger Things duo reaffirms their enduring friendship and united front built over 10 years on and off screen.

In the wake of widespread speculation and online chatter, Stranger Things star Millie Bobby Brown is setting the record straight about her long-standing off-screen relationship with David Harbour, her costar and father-figure in the beloved Netflix series. Speaking to The Hollywood Reporter, Brown emphasized that despite rumors of an on-set rift, their bond remains “united” — just as it has been for the past decade.

The conversation follows a report by the Daily Mail alleging that Brown had filed a bullying and harassment complaint against Harbour with Netflix. The claims, based on an unnamed source, suggested an internal inquiry took place, though it clarified that no allegations of sexual misconduct were involved. The legitimacy of the report remains unverified, with celebrity gossip platform Deuxmoi later describing the situation as a “misunderstanding” over lines on set — something the pair apparently resolved quickly.

Brown, 21, dismissed the noise around the story and instead focused on the strength of her connection with Harbour. “We love this show with everything, and we value our friendship more than anything,” she said, recalling the united front they presented on the Season 5 premiere red carpet earlier this month. “We’ve been doing that for the last 10 years. We have always been united.”

Their appearance at the Los Angeles premiere on November 6 — where Netflix even highlighted their arrival together on social media — further reinforced that unity. Fans and press saw the duo laughing, posing, and interacting warmly, defying the claims circulating online.

Series creators Matt and Ross Duffer, along with producer Shawn Levy, avoided direct commentary on the allegations but stressed the importance of a safe and supportive environment on set. “At this point they’re family and we deeply care about them,” Ross Duffer noted.

The timing of the rumors also coincided with the release of Harbour’s ex-wife Lily Allen’s new album, which includes revelations about their past relationship — a detail that fueled even more online speculation.

Speaking to Entertainment Tonight, Brown further highlighted her connection with Harbour, describing it as “a really special bond” shaped by years of filming emotional, deeply intertwined scenes. “We have a father-daughter relationship,” she said. “It’s been so special to have him on the journey with me.”

As Stranger Things heads into its final chapter, the real story behind the scenes seems far simpler than the rumors suggest — one of loyalty, longevity, and a friendship that has only grown stronger over time.
