The Bachelor in Paradise bartender and Sarah are romantically involved, as a source revealed they've been "seeing each other for months," Us Weeklyreported.
Sarah, 26, just shared their first photo together on Sunday, October 29. The couple went to a Halloween party together in which they were dressed as Eleven and Dustin from Stranger Things and posed in front of a white wall together covered in red handprints.
"Stranger things have happened #happyhalloween," Sarah captioned the image.
Wells posted similar photos from the Halloween bash with the following caption: "11 hangin' out with a 10."
During a recent episode of Wells' podcast with Brandi Cyrus, the radio host admitted he was "talking to" someone who lived in Los Angeles and was therefore spending a lot of time there, according to Us.
The couple had also been flirting on social media in recent months, prompting speculation from fans the pair is dating.
Back in August, Wells tweeted, "Taking applications for #BIP5 bar backs now. Please send references..Preferably from Phil Dunphy. I'm kidding the job is yours @sarahyland," referring to the father of Sarah's Modern Family character.
"I'll start working on my garnishing skills," Sarah responded at the time. "Oh and I require 35% of your tips... or free dogs."
Wells then briefly noted, "Deal."
The pair had also exchanged a joke on Twitter about the hand-waving emoji a couple of months ago.
Sarah reportedly split from her boyfriend of more than two years, Dominic Sherwood, in August 2017.
