Millie Bobby Brown has been acting professionally since she was nine years old and made her big break in Stranger Things when she was only 12. Since then, she's won SAG Awards, been nominated for Emmys, starred in new shows and movies, and created her own makeup line. She's become one of the biggest stars in the world. But despite all of her success and fame, Millie doesn't have it all. Many people think she's secretly a massive diva. As proof of it, there are a lot of videos that show Brown's rude behavior.

Millie said, "Last night, we couldn't even take one group picture because there were like 50 of us. I was like, you need to start killing people off." Her comments caused mixed reactions among fans. Here are all the reasons why Millie Bobby Brown has unintentionally convinced fans she's secretly a massive diva.
