Usually July 4th is when we celebrate America's Independence with a nice red, white and blue themed bash inspired by Taylor Swift's ~aesthetic~. However, this year, there's more to celebrate because on July 4, 2019, season 3 of Stranger Things premieres!  

That's right, we're going back to Hawkins (and possibly the upside down world) once again. Did you know it's already been TWO years since the last season premiered. You might be asking yourselves, how old are these kids now anyway? 

So here's the deal: The show's stars are (obvi) still kids, but they're growing up. As Finn Wolfhard's character says in the trailer, "We're not kids anymore." Keep scrolling to find out how old these kids actually are! 

 

Millie Bobby Brown

At the beginning of the show, Millie Bobby Brown was just a 12-year-old girl. Now, she's a full on teenager with a driver's license and all. Millie is 15 years old!
