Millie Bobby Brown and David Harbour put on a united front at the Stranger Things premiere! Earlier this week, a shocking DailyMail.com report claimed the 21-year-old had filed an extensive "harassment and bullying claim" against David before production for the final season began - and it was said to be "pages and pages" long, leading to an "investigation [that] went on for months." Millie even reportedly had a personal representative accompany her while filming. Resurfaced interviews seemed to hint at some tension between the co-stars as well.
