Stranger Things stars Natalia Dyer and Charlie Heaton may have just nabbed SAG Awards for Best Ensemble in a Drama Series, but the duo has an even bigger reason to celebrate — they're dating!

The couple, who play Nancy and Jonathan respectively, first sparked romance rumors in September when they both Instagrammed photos from a trip to Spain, but refused to speak out about whether they were more than just friends. Now, an insider exclusively tells Life & Style that the actors are, in fact, an item.

“They’re definitely dating. They’ve been together since before season two began filming in October,” the source shares. “[They spend] every waking minute together, on set and off.” Natalia, 20, even brought Charlie, 22, to her hometown of Nashville to meet her family.

But despite their relationship, the Netflix stars didn’t pose by themselves on last night’s red carpet. Instead, they took photos with costar Joe Keery.

When speaking about her role on the hit series, Natalia told Cosmopolitan, “I do see a lot of roles that are, like, the girlfriend or the love interest or the girl next door. Maybe not totally well-rounded kinds of characters — women who are more of a plot device in a way. It was really nice to see a character like Nancy.”

The brunette beauty added, “She does have that love triangle and boy drama aspect to her, but she’s independent and strong, and her main focus is about finding her best friend and solving that mystery at any cost. It’s such a blessing to get to live in that role and bring that to life. And to be surrounded by other female characters while you’re doing it! Having strong women who aren’t damsels is so nice.”
