Currently, as production on Stranger Things Season 4 has been halted indefinitely, Dyer and Heaton have reportedly been housing together in their Atlanta lodgings.
Particularly on Stranger Things, where the show’s intense popularity keeps it going longer than the showrunners initially anticipated, Natalia Dyer and Charlie Heaton have apparently fostered a relationship in quick fashion.
While the relationship was official around the start of Season 2 (maybe even earlier), the young couple kept their romance a secret until Heaton revealed it at the start of 2019.
When working with someone in a close-knit fashion for an extended period of time, sometimes in an intimate fashion, a person might find themselves catching feelings for their fellow actor.
