Millie Bobby Brown stopped by The Tonight Show with Jimmy Fallon on Thursday to promote her epic new fantasy film Damsel. Unfortunately for Netflix, everyone’s attention immediately gravitated to one thing and one thing only: Brown’s accent.

While talking to Fallon, fans couldn’t help but notice that Brown’s English accent was either completely missing or dropping in and out. Social media began filling up with comments asking what the heck happened to her voice, and British users were particularly distressed to hear Brown seemingly assimilate into an American accent.
