After “Cake By The Ocean”-advocate Joe Jonas and Game of Thrones star Sophie Turner spent Halloween together before turning up at Kings of Leon concert in Amsterdam earlier this month, it appeared there might be a new romance afoot. Now, Us Weekly reports that the potential new couple attended a wedding together in Malibu over Thanksgiving weekend—and Nick Jonas’s Instagram has the pictures to prove it.

Turner and Jonas were also snapped hanging out together by a Game of Thrones fan, who posted the photo on Instagram.

In addition to spending time together at the wedding, Turner may have joined the Jonas family Thanksgiving at Mammoth Mountain in California. While co-hosting Live with Kelly last week, Jonas spoke of his family’s Thanksgiving plans.: “We’re going to pick our parents up and go skiing in Mammoth.” But it appears that the DNCE front man may have included Turner in those plans—a source told Us Weekly that the couple was spotted leaving an N.Y.C. hotel together on Thanksgiving evening.

Over the weekend, Turner shared a picture of herself wearing ski gear on Instagram and geo-tagged it to Mammoth Mountain. File this under “Things that make you go ‘hmmm.’”
