Millie Bobby Brown looks all grown up in Stranger Things red carpet event

Millie Bobby Brown, the star of hit Netflix show Stranger Things, just hit the red carpet and she looks like she's all grown up. That's what a lot of people on the internet noticed when they saw Millie's red carpet photo. 

At the Stragner Things red carpet event, Millie wore a chic black dress and an all grown up make up. It was only a year and a half ago that Stranger Things originally premiered on Netflix, but in that time, the actress seems to have matured substantially.

If you look at her face closely in the red carpet photo, some could assume she's already in her twenties. But let's all be aware, Millie is just 13 years old.
