Millie Bobby Brown felt "uncomfortable and disrespected" when a fan filmed her without her permission.
The Stranger Things star felt harassed by a fan over the weekend when she was out Christmas shopping and she refused to be videoed, but the young fan did so anyway.
Getting tearful in a video posted on her social media accounts, Millie admitted: "I'm a human being. It just makes me upset when people try to push the boundary. I'm making this video to say, you have to show more respect for others. No matter who they are or what they do, show respect."
And in a later message on her official page, she added: "I am totally fine now. But was emotional in the moment because I felt uncomfortable and disrespected. It is important to set your boundaries and to speak up. I love you guys. Be kind to one another!"
