Entertainment TV Charlie Heaton Explains Why He and Natalia Dyer Were So Private About Their Romance at First The Stranger Things stars first sparked dating rumors in 2017 and have since kept their relationship under the radar By Eric Todisco Published on February 25, 2020 09:08 AM Share Tweet Pin Email Charlie Heaton is opening up about his relationship with Stranger Things costar Natalia Dyer. In a new interview with GQ, Heaton, 26, explained why he and Dyer, 25 — who play on-screen couple Jonathan Byers and Nancy Wheeler in the famous Netflix series— initially kept their real-life romance a secret. “We didn’t really know what the relationship was,” Heaton told the outlet. “The caginess, anyway, might have been unnecessary.” And according to cocreator Matt Duffer, the pair had chemistry before they even landed their respective roles. “That first audition, we did a chemistry read with [Heaton and] Natalia, and sparks were flying,” Duffer said.

The couple have since kept details of their relationship under wraps. Last month, the pair posed together on the Screen Actors Guild Awards red carpet and held hands in a rare PDA moment. While the two don’t often speak publically about their relationship, in July, Heaton and Dyer opened up to PEOPLE NOW about what it’s like to work together on the beloved series — with Heaton joking that they sometimes get “confused” between their own relationship and their characters’ romance.

We’re really comfortable with each other, so we can play and feel more free, and we can talk about it before,” she said at the time. “There’s that sense of who knows if you’ll ever work together with this person ever again? Who knows? This might be your only chance to play like this.” Both stars will return to the small screen for Stranger Things’ fourth season, which is currently filming.
