Nick Jonas just so happened to reveal some of the memories from the ceremony's photo booth. And lo and behold, Joe and Sophie were in the pictures together.
"About last night table 5 madness... #rp @pariscarney," the "Jealous" singer wrote on Instagram Sunday afternoon. "The bros last night at the Mat & Margo wedding. #petrofftothealtar."
If the Saturday wedding sighting wasn't enough to excite fans, speculation has already started that the pair celebrated Thanksgiving together as well.
On Wednesday's LIVE! With Kelly, Joe shared a few details about his Turkey Day plans.
"Tomorrow everybody flies in together," he shared with the audience. "We're going to pick our parents up and go skiing in Mammoth."
Fast-forward to this weekend and Sophie Instagrammed a photo from Mammoth while hanging out with a gal pal. Just a coincidence? We'll let you decide.
In pictures obtained by E! News, Joe was seen putting his arm around Sophie as they enjoyed a pre-MTV Europe Music Awards event. At one point, it appeared that the "Cake by the Ocean" singer leaned in for a kiss.
"He thinks she's a cool girl," a source recently told People. "She's always been into him, but he's starting to like her more and more."
