Stranger Things fans were left disappointed as Millie Bobby Brown pulled out of the popular culture convention, Collective Con on Saturday.
The 13-year-old TV actress took to Instagram to apologise to her fans and explain why she could not make the event.
"Hey guys, I've never had to do one of these videos before. But I've had to cancel at Collective Con last minute, which is something I've never done and I'm planning on never doing again," she says in the video.
She added: "I just think I've worked too hard and I have to rest as I've had a really long shoot and I'm still filming Stranger Things. I'm sorry to everyone who's going and I promise you guys I'm going to get back to you. I love you guys all, thank you so much for your continued support and thank you."
