Are Millie Bobby Brown And Sadie Sink From Stranger Things Friends In Real Life?

It's easy to fall in love with the characters on "Stranger Things." Not only do they go on compelling journeys, but the chemistry among them is arguably the glue that holds the show together. This is especially true for Millie Bobby Brown's Eleven and Sadie Sink's Max Mayfield, who have had some of the show's most powerfully moving moments thus far, especially in Season 4.

From Eleven's emotionally fueled face-offs against Vecna (Jamie Campbell Bower) and Dr. Brenner (Matthew Modine) to Max's soul-tearing "Running Up That Hill" encounter with Vecna, there was no shortage of moments that saw the two in some heavy places, making it all the more satisfying when they reconnect toward the end of the season. And even before then, their interactions are some of the highlights of Seasons 2 and especially 3.

With the level of chemistry the two share on-screen, fans might be wondering if there is any real-life connection between Brown and Sink. In fact, several of the "Stranger Things" cast members are friends in real life; Gaten Matarazzo, who plays Dustin Henderson, even knew some of his cast members before "Stranger Things" from his days on Broadway (via Express). However, with Sink having arrived on the scene in Season 2, is her real-life chemistry with the other cast members as strong?

Brown and Sink have an extremely supportive friendship

"Stranger Things" stars Millie Bobby Brown and Sadie Sink are very supportive of each other off-screen. In an interview with Glamour, Sink was quick to share her support for Brown's beauty line, Florence by Mills. "I'm so proud of everything Millie [Bobby Brown] has achieved with her beauty line," the actor said. "Millie has always been very involved in makeup and skincare. Every time I would go over to her house, she would have more products than I've ever seen in my life. ... It's funny looking back at the early steps of her developing her products and where she is now, I'm very proud of everything she's been able to accomplish."

Their friendship has also seen plenty of adorable moments, including singing a made-up tune about ketchup and mustard while dressed in red and yellow rain jackets and Sink later captioning a photo of the two of them on Instagram "Ketchup and Mustard." The Duffer brothers told IndieWire that they have no plans to introduce any new characters in Season 5 of "Stranger Things," which will return to its Season 1 roots by focusing on the original characters. Hopefully, knowing the strength of Brown and Sink's friendship, this means we'll get to see more interaction between Eleven and Max.
