The duo perform their new single “I Know What You Did Last Summer” then sit down for a chat.

Shawn Mendes and Camila Cabello are definitely not dating, but they’ve probably made out.

That’s what late night host James Corden will have you believe, grilling the two during a lightning round of questions during their appearance on The Late Late Show Monday night (Nov. 23).

Following the premiere of their music video for “I Know What You Did Last Summer” last week, Mendes and Cabello offered one of their first live television performances of it along with an interview.

One of the questions included if the two are dating, to which they respond, “Well…no,”

“Can I be honest? I don’t believe you,” Corden said. “There’s no way you haven’t made out.”

Mendes and Cabello exchange several awkward rebuttals, including the admission they’ve never made out (though the “Stitches” singer claims he’s tried), before insisting they really aren’t an item. We admit, they played it pretty well.
