Millie Bobby Brown, the 13-year-old star of the hit Netflix show Stranger Things, has apologized to fans after pulling out of a scheduled appearance at a convention in Florida.

It was a Collective Con in Jacksonville on Saturday, but cancelled last minute. Brown posted a video on Instagram saying she’s been working “too hard” recently, and needed to take some rest.

Brown also said, “I’m planning on never doing that again.”

Millie Bobby Brown is a very hardworking kid and should take some well-deserved time off. She manages to do conventions, school, award shows and she is currently filming the second season of Stranger Things. I can understand that she may need some time off because she’s been working so hard but that’s what happens when you become famous I guess. Most of her fans were actually okay with her cancelling the Con and hoped to see her feel better. I would say the same thing because I love how mature she is for only being 13-years-old!
