Millie Bobby Brown and Noah Schnapp's BFF Challenge Proves They're 2 Peas in a Pod

Stranger Things stars Millie Bobby Brown and Noah Schnapp might be connected to the Upside-Down in the Netflix series, but they share an even more special (and far less scary) bond off screen. The teens, who have previously given us glimpses of their adorable friendship, recently put each other to the test by taking the BFF Challenge on Noah's YouTube channel. In the game, each person has to try to guess the other person's answer to a specific question. It's pretty impressive how well they know each other, but the best part of the video is how quickly they derail a conversation. Between Noah imitating Millie's accent and Millie smearing Sharpie on Noah's face, it's hard not to crack up watching them!
