Sarah Hyland and Wells Adams went as the “Stranger Things” kids for Halloween, and there’s definitely something strange going on here…

Celebs went all out this weekend with their Halloween costumes, but one pair really caught our attention. Sarah Hyland and Wells Adams dressed up as Stranger Things kids and got everyone talking. Their costumes were spot on, but we’re starting to wonder what those two are doing hanging out together.

According to Us Weekly sources, Sarah and Wells have been “seeing each other for months.” Wells recently mentioned on his podcast that he was “talking to” someone, but he didn’t drop her name. However, you might have noticed that the Modern Family star and the Bachelor Nation favorite have been flirting with each other via tweet.

The possible romance seemed to start all the way back in August.

At the time, Wells tweeted jokingly that he was accepting Bachelor In Paradise bartending applications. “Preferably from Phil Dunphy,” he wrote, naming Sarah’s character’s dad on the hit ABC sitcom. “I’m kidding the job is yours @sarahyland,” he joked. She responded with, “I’ll start working on my garnishing skills. Oh and I require 35% of your tips…. or free dogs.”

How cute, right? They make a great couple, too, judging by their Halloween costumes.

Here’s Wells Adams and Sarah Hyland as Eleven and Dustin.

But maybe not how you’d expect.

Over the summer, Sarah and Dominic Sherwood broke up after two years together. But just recently, she tweeted about the pitfalls of being single. She wrote, “The problem with being single isn’t the fact that you’re alone. It’s that you can’t puppy dog eye a guy into getting you Starbucks in bed.”

Which must mean that she and Adams aren’t a serious couple yet, just hanging out and slaying Halloween together. Which is not a bad place to be at all. Though given his amazing bartending skills in paradise, Wells would likely be totally into schlepping for some Starbucks.
