You get ‘no’s, a lot of ‘no’s, before you get a ‘yes.'"

1 What's Next For Millie Bobby Brown?

So, what's next for Millie Bobby Brown? She might be 17, but to call her a 'breakout actress' is not suitable anymore as she'd made a big name for herself in the acting landscape. Currently, the actress has a plethora of projects on her horizon, including the 2022 follow-up of Netflix's Enola Holmes. She's also been keeping herself busy with her beauty line, Florence by Mills and will definitely add more interesting projects to her acting portfolio.

"I’m only 17, but at the end of the day, I’m learning to be a woman. I’m learning to be a young woman, being a young girl, people watch you grow up, right? And they’ve almost become invested in your growth and your journey. But they aren’t ready to accept the fact that you’re growing up," she told MTV about fans who struggle to accept that she's growing older. "I wear a crop top and people are like, 'She’s 10.' I’m like, 'No…I am 17.' That’s a thing that girls do. Or I wear high heels. Or I wear an outfit to an award show and they’re like, 'She looks 50.' No, it’s because you’ve watched me since I was 10. That’s why you think that," the star continued.
