Shawn Mendes and Camila Cabello are on fire right now! Their duet, "I Know What You Did Last Summer," is the stuff of dreams — but there's a bit of drama over the true nature of their relationship. While on The Late Late Show with James Corden, they both insisted that they're not dating. However, the host wasn't buying it!

"Can I be honest?" James asked. "I don't believe you. There's no way you haven't made out."

“We haven’t really. Every time I tried to make a move she just like, swears me off," the "Stitches" singer said.

When James asked if Shawn had ever made a move, he said, "Yeah, totally."

Meanwhile, the Fifth Harmony singer insisted, “He friend-zones me. He calls me kid!”

The host kept trying to get an answer, prompting the singers, “Let’s get to the bottom of this. You’re saying that is completely not true! He has never leaned in?”

“He has never leaned in! You have never tried to make a move," she said.

Shawn joked, "I'm telling you, every time I try to make a move, she's like, 'No, you're weird.'"

But Camila kept insisting that her collaborator has never once tried to go for it.

Um, looks like someone doesn't have their story straight!
