• Natalia Dyer and Charlie Heaton play Nancy Wheeler and Jonathan Byers, respectively, on Netflix's "Stranger Things."
• The two started exploring their feelings for each on season two, released October 27 on the streaming site.
• If you were shipping Jancy/Nanathan on screen, many are convinced they've been dating since at least January. There are photos of the two traveling together and holding hands.
• Neither actor has confirmed they're dating.

Nancy Wheeler and Jonathan Byers may not just be an onscreen couple on the second season of "Stranger Things." Photos of the two out and about holding hands and traveling have fans convinced they're dating in real life, too.

In the second season, Nancy breaks up with Steve and finds herself gravitating toward Jonathan who she bonded with in season one after his brother disappeared. If you were feeling the on-screen chemistry between the two there may be another explanation.

Natalia Dyer and Charlie Heaton, who play Nancy and Jonathan, have been spotted traveling together multiple times from Los Angeles, sending each other cute messages on Instagram, and were recently caught holding hands while in New York City.

It's no secret that many of the "Stranger Things"cast are close friends, but it has fans thinking Dyer and Heaton are more than just good pals.

Take a look at the evidence.

Fans first thought something might be up when the two were traveling together in Spain in September 2016. The two shared Instagram posts while abroad.

The two have also had a few matching Instagram photos.

You couldn't see the person on the other end, but both Dyer and Heaton were posed in the same way eating ice cream cones.

The two were rumored to be dating in January 2017 when they showed up together at the SAG Awards and looked awfully cozy on the red carpet.

Then they were traveling together twice in January leaving from LAX airport. One time was right after the SAGs. On January 9, Heaton had his arm around Dyer who was covered up to travel incognito.

Pay special attention to Dyer's feet. Those may be Heaton's Converse she's wearing. 

Two days later, Heaton asked the actress for his Converse back while wearing her shoes in an Instagram photo.

But it's a photo from October that has most convinced they're together. The two were spotted holding hands in New York City.

An anonymous source who spoke with Life & Style magazine said the two have been seeing each other for over a year prior to season two of "Stranger Things" filming.

"They’re inseparable, and spend nearly 'every waking minute together, on set and off,'" said the source.

Neither Dyer or Heaton have confirmed they're officially dating. Back in March, the two played it cool when they were approached by TMZ outside LAX airport.

"Whether people are dating or hanging out, I think that our cast just is cool with each other," Dyer told TMZ. "I mean, I won’t speak for anybody else but it’s been, you know … We’re all one big family."

One big family or not, the two are currently traveling again. This time in Paris.
